I own a couple each of both Genesis and SA.

The adjustability of the Genesis is nice, but the peep housing is rather wide in diameter. On my peep, the center poertion would occasionally creep out of position and you'd have to realign it. I was told that if you pop the center out and rough up the edges with sand paper it will not do that.....

I've gone back to a regular peep or SA peep with interchangeable apertures. It's just me, but I don't care for how wide the Genesis is. With good quality strings and a little tinker time, I have no problem getting perfect alignment on peeps. SA does make two different peep housings, 37* and 45* depending on what A-to-A length your bow is and drawlength combination. Check their website for the charts on which would work best for you....

just my opinion...
