I use a #9 for silnylon without any problems with the thread, maybe your tension is off a bit? I think I use that size because that what was recommended by some manufacturer. I do recommend Gutterman polyester thread.
My problem is it feeds great, but does not want to stay put. Needles wise I am using 90 14, and 69 nylon. Which is actually small on the needle side, so I am not worried though 80 12 is recommended. Sil is really thin. There might also be a presser foot tension problem if it is not feeding. Not if it is normal, it's a non-adjust, but a lot of people are using some rescued old machine and who knows what got twiddled.
Normal problem with tension is failure to adjust the bobbin. Get that as low as will work then screw down the upper tension to center the knots. SO long as the material has good contact, there are no points for higher tension in backpacking gear. And the fabric will tell you.
