Not much! Im still working out some kinks it has. The 350 is super plush like butter! So, I actually need to stiffen it up some! Make her ride a little higher in the travel, I had my durolux set perfectly for me so within time I will this marz 350 fit and chipper for my liking.

 This thing is a super smooth beast that easy to whip and flick into fast flowing fun while in harsh conditions! I love it!

 Thank you buddy!
