Has anyone actually ridden either of these frames yet? I've currently got an 05 cowan and love the geometry and feel of the bike even though I use mine more for more downhill/aggressive trail riding than dirt jumping. Spent some time at Downeiville and Northstar on it this summer and ride the Tam and Annedel in nor cal on a regular basis. How do you think these two frames would do on trails? I figure since I like the feel of my bike minus the harshness of a hardtail on rocky trails these might be a good match for me. Being a light guy i'm thinking i'll be fine with 4" of travel. Do you agree and if not give reasons? Also it looks like the only difference between the two frames is the rear dropouts and the pivot point on the rear. What are the pros and cons of each for the type of riding I would be doing? All the parts on my current Cowan are stock except for the forx that are now Fox 36 Talas RC2 and would be put on the new frame. So let me know what you think.
