just sent my short barrel back to RNT for some tuning and (hopefully not) repairs.
The Coco's are nice, but there would be some fightin' if someone ever tried to get my Bois' D'Arc shortie from me.
i haven't blown an acrylic short barrel and not sure i would want to. IMO the shortie's best attributes are the low end duck sounds it makes. quacks, chuckles, and soft greets to really get those ducks in close seem to be the strong points of that call. i can't imagine using a "loud" shortie.
for an acrylic i would probably get an Original or maybe another brand such as Echo.
