I'm kinda in the same group as mauser06. Having shot a lot of field shoots years ago and indoor target and 3D for the last 15 years I can feel whether the bow is level if I'm on fairly level terrain so rarelyever look at the level. If I'm shooting sidehills and/or up or downhill I'll take a glance at the level and correct as necessary, but it doesn't take long to do so nor do I dwell on the level itself.

I have sights with levels on my hunting bows also, but getting practical about it I don't use them.Most all my hunting is from treestands for Pa. whitetails ans shooting maybea maximum of 30 yards there just isn't any way to cant a bow hard enough to throw off the shot by much.

For that same reason I have no use for any kind of capture rest, too.
