yea the 157 should be much better than the 164. actually i would definetly ditch that stick and get a new one if you plan on doing a lot more riding this season, its probably holding you back a bit.
if you dont want to spend as much money heres a few suggestions:
Rome Reverb Rocker
Signal Park Flat
If you can find and Arbor Blacklist in 157 get that is sposed to be one of the best out this year
Dude, suckin at somethin' is just the first step to bein' sorta good at somethin'
