Would you consider a Lib-Tech TRS (non-hp) a stiff board?
I picked up a 162 TRS last season and overall the board is pretty awesome. I'm still progressing my riding, I'd say I'm a solid intermediate groomer rider. However I'd like to start trying to do some butter tricks as well as still bombing around the mountain and keeping up with my friends who ski.
Trying to do a simple tail press on my TRS is really tough as the board feels really stiff. On lib-tech's scale they say the flex is 7/10 (its all relative of course) However this review from the-house.com says its a flex of a 5 (granted this is the HP version and I'm assuming its not a 162 they were reviewing)
I have a TRS 157 and would give it a 5-6 on stiffness, its easy for me to butter, and is decently playful while still being a hard charger. Like you said size makes a big diff in stiffness. Im 6" 180lbs, 157cm is perfect for me, I normally ride 159 but wanted this to be my playful board.
