you got me! I am not really made any committment one way or the other.. I totally enjoy my 630 and considering I have had next to "none" when it comes to the mastery classes", I have pretty much been winging it. Fortunately I do have a friend that worked for the no longer existing lqs. and she brings her lap top and tatting stuff that I made up for her and we have a time frame for mastery lessons and then tatting time for mastery lessons. win/win all the way around. I think she will using double shuttles before long. I won't,, because I can fumble perfectly with just one.
Thanks. That was one of the best over all complilations (?) of a vs b that I have seen on any machines.
