There are a lot of different reverse cambers and before going over those, it is important to note that others ingredients are critical in making a board perform well. You have to look at the glass technology (stiffness, flex, torsion), wood core (pop,how lively and responsive), sidecut (edge hold, transition from edge to edge), the base tech (beveled base, etc..),and the overall construction. By now you must think holly sh#@T, it is already confusing enough (for most snowboarders) to think about the cambers so there are way too many parameters!!!
Well sorry but it is like having a car with a Ferrari engine and tires that are used for a French moped, you are not going to go very far. So even if you are looking at two boards with the same base technology, they may not react the same at all. But hopefully I can make your search easier, that is the only purpose of this post. The best is to try boards and if you can't, try to read reviews, call customer service from the brands you are interested in.
Standard camber: convexe arc between the two contact points (parts that touch the ground when the board lays flat)..what dinausaur like me have ridden for most of snowboarding life.
Pros: transition for edge to edge, control at higher speed, pop, chance to reposition yourself during XXL landing
Cons: takes more effort on the legs to do presses, less forgiving for normal under/over rotated landing, shorter butters, difficult to lock presses.
Tech name: Lib Tech Banana (I am just kidding); Rome positive camber, K2 camber, etc..
Note:Bataleon TBT uses a positive camber but has a triple base technology which gives a lot of added benefits, one of them is that the contact points are raised.
Reverse camber: Rocker the whole length of the board.
Pros: Ease for initiating turns and presses. Great if you want a board specially for practicing your rail killing skills and butter like nobody's business. It creates a more playful ride
Cons: lack stability and edge control giving it a twitchy feel. Loose a bit of initiation and turn exit control at higher speed. May lack pop (but can be compensated by the core and glass tech).
Tech name: Lib Tech Banana, Salomon Pre-sure Rocker, Forum Chilly dog, Technine 9Rocks reverse camber, Flow I-rock ( except flat camber at the tip/tail on the contact points)
Centered Rocker:A long mid-body of reverse camber combined with straight camber in the nose and tail.
Pros: good blend of control on edge and playfulness, good powder ride
Cons: less pop than camber boards or rocker-camber boards
Tech name: Rome Reverse-MTN, Omatic B.S (+beveled edges is another real important factor giving additional charactheristic), Lib Tech Banana BTX
cam-rock: like a standard camber board except it is less pronounced and you add a bit of rocker between the tips and bindings
Pros: like a camber board except gives a bit of a looser feel, better playfulness as well as flotation in powder
Cons: Bit less playful, not as great in powder than reverse camber, flat camber or powder rocker
Tech name: Nidecker CamRock, Yes snowboard, Salomon Wingtips (very light rocker just contact points that have been raised), Rome HybridCamber, Signal Wavelength, K2 catchfree
Rocker-Camber: a light rocker between the bindings and a bit of camber between the tips and bindings (don't rise your eyebrow, it is the exactly what you are thinking of: the contrary of a cam-rock).
Pros:Stability during high speed cruising and solid landing as well as excellent pop for ollies while the rocker gives good control for presses. The pop is usually better than on a CamRock board. and Thanks to the centered rocker this will be enough to make it a great board for powder as well.
Cons: NA except if you are 100% jib, butters you can find a better suited board for that category
Tech name: Nitro Gullwing, Never Summer R.C, Lib Tech Banana C2
Note: Inca used to do two individual camber under each insert..not quite the same than rocker-camber but the idea is the same and I will call that dual camber.
3 stage rocker: a light rocker between the bindings and a bit of rocker between the tips and bindings, which counts for 3 rockers on the whole board
Pros: great for pow,jibs, guffing aroud. A lot like the reverse camber, except there is more edge control
Cons: like reverse camber "lack stability and edge control giving it a twitchy feel. Loose a bit of initiation and turn exit control at higher speed. May lack pop (but can be compensated by the core and glass tech)"
Tech name: Burton Vrocker
Powder rocker: rocker from the tips to the front bindings and then normal camber throughout the rest of the board
Pros: By applying pressure on the tail (camber matches the board set back stance) that leads the entry rocker to lift giving the best control, power & speed in deep snow. If you surf and have the opportunity to ride a lot of pow..that's the board for you, as close as it can get to the surfing experience. The regular camber part allows a lot of snap out of the tail allowing powerful turns completion.
Cons:excels in powder but not the best all terrain board design. Directional design so it can be difficult to ride switch.
Tech name: Capita Mono reverse flat kick, Burton S-rocker, Rome S-camber
Zero Cam: the board is flat (of you course it isn't a door,you still have a tip and a tail). distribute pressure on the snow in a neutral fashion.
Pros: Some people refers the feeling as if the board had been broken in after few season. I would not go as far as some manufacturers saying it is the best of Camber and Rocker board. however I would say it is a fair compromise, with a flat camber you take the pressure off of the contact points but don't pull them away from the snow,so you get somewhat the responsivity & control of a camber board and the playfulness of a reverse one.
Cons: not as good as camber boards for XXL landing, a bit less control at higher speed and you will not get the extrem toy feels of reverse camber boards.
Tech name: K2 Flatline, Salomon Flat profile, Nitro Zero camber
Zero-Rocker: zero camber between the bindings and rocker at the tips & tail
Pros: Zero Camber between your feet focuses control, it gives a solid platform for stability while riding & landing. Subtle rockers lift the tip and tail (the usual contact points on camber board are lifted), giving you the power to press and a hookfree feel in addition to better pow riding than regular camber boards.
Cons: Not as responsive as camber board but at some point you have to decide cuz you can't get a board that is the best in the powder, the hardpack, park and street. So great compromise except if you are a 100% rail freak and you like to put butter on everything you eat.
Tech name: Capita Dual Reverse flat kick, Burton P-rocker, Ride LowRise rocker, Salomon Pow rocker, Rome Reverse-jib camber, DC Bender Anti-Camber, K2 powder rocker (front rocker more pronounced than back one, see benefit of powder rocker), K2 all terrain rocker (rocker from the inserts to tips/tail), K2 jib rocker (rocker just before the tip/tail)
