I used skimmer socks last years and switched to knee highs this year. These seem to do as good as job as the skimmer socks if not better. The 'holes' you have you in knee highs are about the size of a pencil lead. The holes are small enough that stabilizer does not pass through them. I placed them in front of a return so that water hit them and that was much more efficient that putting stabilize in through the skimmer imho.
I don't have any more fine stuff this year than I did last year in the pump basket. I not sure, but I think the size I use are 'one size', whatever that means. I suppose the bigger the size the smaller the hole. But they keep grass out.
They do a good enough job that I seldom have to backwash.
