After a 30 mi. ride yesterday my butt tells me the Avatar is better than the Arrowhead but only slightly. I think some of this is due to saddle set up. I noticed that I wasn't spinning as well and I'm sure it's a matter of the fore-aft saddle placement. I'm 5'9" and 185 lbs, having lost 12 lbs recently, and I think the weight loss has affected comfort on my original Selle Italia Flite Gel saddle. If I can't get this dialed in properly I'll be on to another saddle search.
