I use a variety, too - I stash batting when it's on sale so I keep a few different cotton and poly batts on hand. I like most of QD's battings, but I also tend to like a thinner batt. QD does have a "Select" line that is thicker than the Request line. I've only used Hobbs 80/20 once and unfortunately I really didn't like it, it felt icky to me. It was fine once it was in the quilt though.
On the wool that you got bearding - are you longarming it? I've used their wool batt once and really liked pretty much everything about it, but I tied that particular quilt. I had intended to get more next time I spotted a sale, but not if it beards on a DSM!
