You should buy an FT-12, BT-4 Slice, and Enmey. For a few hundred dollars you can decide for yourself where you are headed. Beat them up, shoot them thousands of time, loan them out for people to use, play with them yourself, work on them, etc.
We went with the Enmey's, and there are minor hiccups like any new product, but overall I am stunned at their performance, and any problems we have had were promptly handled by GOG.
PM me or call me if you want to talk some more.
