I'm running the Taylor Freelance +10s and I've been very happy with them. I have a CZ Custom +20 and it binds up pretty frequently. It may be something I can sort out but since the Taylor mag extensions just work I haven't messed with it much.
I was at a Level II match just recently that required the carbines to be flagged and bagged in between shooting. I'm not sure they would have gone for something like this.
