Yes, Jeff changed usernames. SB stood for Switchback and now using his Bowtech he wanted a name change not unlike many. I've been thinking about loosing the Bowyer, everyone refers to me as Rob/PA anyway.

GMMAT is a username he has on another site and thought it appropriate for here as well. It's on the limb of his bow and if he wishes, he can expand on the subject more.

I'm just sayin....
