Ditching the peep is not a bad thing. However until you get very good at it, I wouldn't consider hunting without some form of optical alignment device. I tried just the kisser route and ended up making bad shots if I was in an akward position at the shot. Having something else other than the kisser seemed to add that bit of extra assurance.

On one of my hunting rigs, I took the peep off and use a kisser button and a NoPeep. The kisser makes sure I get the correct anchor and the no peep works great. That being said, I am a real accuracy junkie so my current bow has a kisser, NoPeep and a regular peep sight. Get them all lined up and the arrow is just about guaranteed to hit the mark.
