Low friction rings on the main as reef points

[B4A]

Hi all:

I have a single lines reefing system on my 56 sq meters (607 sq feet) main sil.

The stainless ring creates a lot of friction and I was thinking of replacing it with an Antal low friction rings.

Questions:

1) How do you lash the low friction ring? I was thinking about keeping the stainless steel one on the opposite side.

2) How big should I go with the low friction ring?

3) Can anybody who has done it post some pics and feedback?
