What is better, or is it just a matter of personal preference? I use a 1" loop @ 29" draw now, but I ordered a new module which will increase my draw to 29.5 or 30" whichever I choose, and an extra 1" on 30" will be too much, so I may just using the little brass buttons if it really doesn't matter. Do loops help with accuracy or something? Let me know what you guys think/know from experiance. Thanks for the input.
