When I am working on a quilt, I normally wind 10 bobbins before I start - though I do so with my silver 15-91, as I can get a much tighter, even wound bobbin that way. I do use my fingers to guide and apply more tension as I'm winding.
I use them almost exclusively with my APQS machine too. There are a few reasons for this:
1. I'm a little lazy. I'd rather spend time quilting than bobbin winding. Stopping to wind a bobbin seems to ruin my momentum.
2. They hold more. Especially with a LA machine, you notice this very quickly.
3. This is the big one for me: Tension. A pre-wound bobbin, the good ones at least, will have consistent tension from the beginning of the wind to the end.
For the longest time, I thought my Pfaff 6122 hated the pre-wounds. My supplier sent me some samples and the thread kept snapping. I threw them in the corner and forgot about them until Lucey arrived. One day, putting one of the pre-wounds I use on her into her case, I noticed that some of the bobbins were wound fuller than others. The reason I noticed is that a loop of thread had puddled off the bobbin inside the case, wrapped around the post and snapped the thread.
Aha! Pulled about 10m off one of the bobbins that my supplier had sent and put them in the Pfaff. No more trouble. Now I use the left overs from Lucey in the Pfaff. (Both use L bobbins)
As an aside, the L bobbins also work in the 15 cases - at least the horizontal ones. I haven't tried a vertical yet. I use them in my Kenmore/Janome too. One of these days, when life settles down some, I will try out a vertical case just to see what happens.
