I really enjoy this topic. Everyone has different tastes for batting, and I have 5 or so different ones on hand to give the choice to people.
Warm/Natural, Hobbs 80/20, Hobbs poly, Hobbs Tuscany, and now Legacy 80/20 and washable wool, oh yeah Legacy 100% cotton. 7 different kinds.
I have a batting room.
Right now, I really like the Legacy by Pellon, 80/20
