I had DanO make me a predator fleece one this season, totally forgot how comfortable they are. I still grab my mantis 95% of the time as it works for me and is a all-in-all, but I have no problem using my RCH and fleece saddle and feel 100% safe in it. The plus side of a fleece saddle is they are READILY available and thus there is no limit of waiting to get a saddle. Took me under 5 minutes to put the last one together (already had the Amsteel dogbone.
To tell the truth, I am surprised they didn't catch on more.
