Has anyone used these Gapless rings in their motors? N/A, FI, or nitrous?

Boosted LS1

I've got them for my turbo motor which is built but not installed yet. The only problem that I have seen posted on this BB is that they suck oil down from the guides but TS warn you about the extra high vacuam that they pull and advise you to fit restrictors in the breather system. I used them in Rover v8's and like them.
