Re: Sight Rings
really depends upon who you talk to ....Mike Braden for exaple teaches that you anchor and bent at the waist ... George Ryals teaches to draw on target .. center and anchor... Reo Wilde teaches a combination of the 2. (all 3 of those people are way smarter than I ..and better shots than anyone on this site of the 3 .. Mike Braden is the only dedicated 3D shooter.. Ryals is a paper puncher ... Wilde shoots alot of paper and Field with the odd 3D) I dont agree with the form having to be a perfect T ... as long as your release elbow is in the same plane as the arrow you are good (not off to the side but straight back ... elevation doesnt matter)
as Far as centering the ring ... If you center the ring around the inside edge of your peep your pin will be natuarally centered as well... if you cant see the the sight housing in your peep I suggest getting a sight that allows you to move the sight out in front of your bow a bit more or get a bigger peep(I dont like the idea of bigger peep for accurate shooting)
Regardless of how you center your pin the key is to do it consistantly. 4Pt... please dont take this the wrong way ... but I find it hard to believe that you are consistant in your shot execution ... the anchor might be consistant with the 2 points that you mentioned ... But think of it this way, What is more stable? 2 points of contact ... or 3? Stand on your tippy toes and be stable .. dont wiggle .. stand absolutly still .... Hard aint it? now stand on your tippy toes and bend slightly at your waist and place your hands on the desk in front of you .... way easier to stay still huh?
As Bowwalker pointed out ... the ring on the sight housing is a visual cue for consistantcy and stability ... without it .. you might be close to centered all the time but could be up to an 1/8" out of center ... at 30 yards that could translate to 4" or more.
when was the last time you shot a 300 30X paper or an up round of 3D (200 plus on a 20 target 3D course)?
have you ever?
if the anser is "not last time I shot those rounds" or never ... then you have work to do my friend ... Like all of us.
Just my opinion on the subject at hand
