Consistancy is the major factor because shooting out of a treestand causes most to shoot with improper form, couple that with not anchoring the same as level ground, not having a peep for most will cause your arrows to be high and low depending.
There are so many new larger diameter peeps that low light is rarely a concern along with the new fiber pins. Like I've said many times within the sight question posts, I can still see my pins when it's too dark to shoot the deer with my naked eye.
When someone has a consistant anchor point and maintains consistant form, peeps are less necessary, on level ground...treestand shooting causes other situations to overcome.
I'm not a fan of using both, a peep and a kisser but I recommend one or the other.
Also, for everyone reading, don't misinterpret "no peep" use with not having anything. There is a product called "No Peep"....it aids in alignment.
I'm even confused on what you meant Germ..
And as far as not having a sight, The Nuge does it, he cants his compound and shoots instinctively along with all the other longbow and recurve guys....on an Allegiance, I highly recommend a sight.
