So I'm just a couple days out from ordering a new board, I'm an intermediate rider looking to just make a jib/park board so I decided on the artifact rocker after test riding the signal pro rocker. My question is what size should I get? The 150 or the 153? I'm 6 feet 160-180lbs depending on my wrestling schedule. The guy at my local shop advised me to get the 150 for a park board but it seems kinda small for me, I rode a 148 last year and it was fun for spinning and grabs but seemed unstable when I picked up any speed. Any advice or opinions on this would be greatly appreciated!! SHREd On!!
