I agree with todays bows and postive stop back walls both are really not necessary.

I use just a peep and feel that's a better system than just a kisser. The size of todays peeps are big enough that light through them is No longer the problem it was a few years ago when drilling them out was the norm. Used to 1/8" was a Big peep. I know shoot a 3/16" Meta peep, but 1/4" & 5/16" sizes are available.
