I'm currently riding a DH bike with a 2011 Fox Van R and am thinking about upgrading to a an RC4. I had an RC4 (Tekin tuned) on my last bike and I liked it a lot (apart from the 2010 model exploding and having to be replaced), but am wondering if I am a good enough rider to notice the difference between the two. Because I haven't ridden my latest bike (demo) with an RC4, I don't really know how much better it would feel, or, if I would notice the differences. Has anyone ridden the 2 shocks on the same bike? Apart from the lack of adjustment, will the Van R have a similar feel on the trail?
