alex u cant really ask that kinda question, those are personal opinions
it can be 10 nood to nivek but to you it can be 1 stiffer, and all depends on that person,
and how it feels to them, and another if someone is lets say 5"10 weight 140 on a board thats really stiff
isnt gonna be to a guy lets say 5"10 200+lb more leverage get what im saying?
neways im pretty sure, what type of boarder you are, just go look around and see how other ppl who rode the boards, compare with diff type of board lets say since you ridden burton dom, find out how others might compare to that, cuz straight random answers from just asking how is this and how is that, is just useless info to you, cuz everyone is diff and thinks diff.
hope this might help.
and to comment on gnu and slay, those are i say diff type of boards then what alex is looking fore
