I have a Brother 350SE, then added the Brother PE770. I, too, found that slowing the speed down on the 770 seemed like it helped - don't know if it actually helped the machine or my feeling of control. :-)
Speaking of hoops - has anyone tried the continuous feeding and embroidery with the Snap-Hoop? I have read everything I have been able to find on it and have been toying with the idea of getting one for my 770 but wonder if anyone has had experience with it?
