presses and butters are good learned on a stiffer board, not a super stiff board, but something stiffer than a jib board that's for sure.
take the beating, and learn when it's applicable to press.
reverse camber boards are cheater boards when it comes to presses and butters. Nothing wrong with that, but if you take a regular camber board, or a hybrid camber board and pressed that, it's a lot tougher.
it's really all about balance and where to apply it.
jib boards have no torsional stiffness, so they won't hold an edge worth sh!t. makes high speed edge holding crappy. You'll haul ass in a straight line, but when you want to tip the board on edge, you'll find that it won't even go in the direction you want.
Look at board construction, as there is a few different types of laminating to stiffen the core.
biaxial, triaxial, quadaxial, and a combination of each of those with carbon stringers or carbon sheets tossed into the mix. Carbon is used to increase snap/pop/kinetic springing action.
Another thing to consider is edge detuning. Bevel the base edge of the board to allow the board to be less prone to edge catching, this helps for rails and boxes as well, less susceptible to hang ups and catching.
and then it's all a matter of foot/leg/body pressure. once you know how a board flexes you can butter spin all the way down a hill if you wanna.
Then proper butters can lead to flat ground flips, and compression spins, and eventually you can butter revert spin off of a table. those are fun.
