For what your doing I'd go with the 450 shocks. Elka is for sure a better shock but you dont need to spend that kinda money. To get an elka with remote rezzi your looking at about $1000, And you can pick up a pair of brand new take off 450 shocks for $200. You could get a set of used arms and 450 shocks for the price of just some elkas. So if I was you I'd be on the look out for some +2 arms and 450 shocks. I personally run 2009 yfz 450r shocks and a buddy of mine has elkas and I cant tell the difference by riding it, But I'm not hitting giant jumps either but in the trails whoops and all that they're awsome.
