i like a little bit stiffer of a ski but not like crazy stiff. im fairly big(6'1" and 180lbs) and i will dominate a soft ski and it will be all over the place. and what are the advantages of a soft ski? basically to ollie and butter, thats it. a stiffer ski though, helps on big jumps, landing backseat, skiing lines with them is way better, cliff drops, powder, crud, groomers, high speeds, i dont think it matters when it comes to rails and boxes though. i use some 05 skogens as my all mtn/park ski and there perfect, not to stiff even though it can be kinda hard to butter with them(idk, maybe its me) and there stable on landings of anything wether it be cliffs or jumps, and they own the trees
