I shoot compound without sights. Used to use fingers too, but had too many bad releases in the past and switched to a release this year after a 10-12 year hiatus from archery.
I'm not sure on how I aim...I think it's down the shaft, but I've done it for so long that I just do it.
There was one year that I tried sights and got all screwed up. Took the damn thing off and re-taught myself to shoot without them.
This past year, I dug the bow out of the basement, had it checked over by a shop, and shot it. I thought I'd be all voer the place, missing the targets and rusty as all get out. However, that wasn't the case. While not pinpoint accurate, I was still "in the kill zone" at reasonable distances.
The rest is a plain-jane "pressure" rest that I left on from my finger-shooting days. I've got it tuned OK (I believe) for my release.
Looks like this:
