Honestly, yeah its all preference. I used to ride the 2010 T-Halls, loved them to dead but they were just a little too flexible for me, sometimes i'd land backseat and my skis would over flex and it'd just fall, but they were 172 and I was probably 5'10 5'11
Now I'm 6'0 210 and i ride the 188 Klint Primes. A little fat ski but once i "broke them in" i really got comfortable with them, i can butter kind've but was never really my strong point. I feel like the more you ride your ski and when you take it on different terrain than just park somedays, you get a better feel for the ski and can understand where you excel.
Also I dont know if it's just me or what but i had originally had the LOOK PX12's on my skis (shitty bindings broke them 7 times) and this weekend i got the FKS 180 for $70 with a discount of my bindings break a lot, but im noticing I'm overall just riding better, stomping better tricks, and i feel "lighter" like i can ollie and nollie a lot better. Not sure if its the bindings or im thinking this. K bye!
