Conan, I just received my SRF Sight from 3 Rivers . Have the E Bracket and the B aperture on my Dalaa. New Hoyt limbs (34#) to improve my form, the sight to play with, and the light limbs wont hurt in test driving the SRF.
The top part is dead on at 10yards, the center wide portion at 20 yards, the bottom portion dead on at 25 yards. Got some 4" groups at 25 with a verticle bow and surprise of surprise with a canted bow at the same range(30-40deg cant). The wide portion necessitated I line the arrow up for windage to decrease group size. In ordering, for me so far, the C aperture is best for corner of mouth anchor with high speed bows> 170fps, the B for 150 -160FPS, the A for high anchors, real slow bows, and 3 finger under shooters. Dave has a good way to measure range required for the respective sight apertures on his web site. I used my point of aim reference to set the sight initially, only one small correction necessary. In a short time, it is the easiest sight system I have used. For me, much easier than pins, and arrow tip, and a mystical kind of ease to putting arrows where you want them. This post is at the risk of someone telling me I m smokin' dope. This is just what Ive discovered in the short time Ive been playing with it. It truly feels like I m cheating with my Dalaa. Arco Nudo be damned.
Estacado
