So far I've got a few rings to look into that I've never used/ heard of before.
My dislike for aluminum rings spawns from stripped screws, and bent rings... Not during use but during installation/removal. Personally I've never had any luck with them. Not trying to say they are weaker or starting anything... Just saying personally I prefer steel.
S&K will most likely be my next ring purchase. I like a company that stands behind their product.
