Welcome to the new and improved Proflex / K2 Tech Forum!
Shovelon, what fork do you run?
Is it on your oz? I started running a 130 on my 4000 last year and it felt a little tall at first. I think its a perfect match with the 5" travel rear. It isn't cumbersome on climbs unless you stand up and hammer. Mono pivots seem to climb much better seated anyway.
Here's mine. The steering is a little slower than my other full suspension bike but it goes down hill reeeeeeally well. No complaints. I switched from a 100mmm travel fork to this adjustable travel (115-145mm) Nixon.
