I just bought a Trykon and about to have the pro-shop set it up. I've always hunted with longer ATA bows and never used a loop. Do you guys think a loop is necessary on theTrykon with a 33" ata? I've shot it without a loop in the shop without a problem but I didn't know if the angle at full draw, 28.5", would pinch the nock too much??? If I can get away without a loop I prefer not to use one.
