On positioning slippery nylon fabrics in sewing machines

All of our attention lately has been getting our first product lines ready for sale. Horrifically, this means no backpacking.
I've also been thinking that I want to share some of what I have been learning about sewing these lightweight, slippery fabrics. Bear with me, I've only been sewing for a couple of years and it's nearly all been on Ardeth products.

I don't pin. I don't even pin, then remove the pins as I am sewing up to them. But, I do pin to set up my pieces.
A quick pin at my starting location helps to keep the slippery nylons that we work with in place until I can get a few stitches in, but after that, I remove it.
Granted, I am usually on my needle-feed machine, so that helps greatly.
