I don't know how you figure that, but whatever. Shooting low or high is no different than shooting left or right. Something is off.
And all I said was it could be as simple as a sight adjustment.
Why would someone go thru the trouble to tune their bow for bh's hitting left or right, but not up or down?
They wouldn't. I never addressed those issues.
Also not sure what centershot has to do with a broadhead hitting low or high either.
I mentioned checking center shot when you touted moving the rest and nocking point as a "fix" for hitting low. Assuming center shot and spineare correct.....you need to adjust your sight. Period. Center shot, first. Sight adjustment last. I would never adjust my nocking point without checking center shot/level....and simply hitting low wouldn't tell me the nock set or rest was "off", necessarily. I'd also ALWAYS adjust rest height first (before nocking point) if it were feasible.
As far as nock pt adjustment...I can adjust mine in a matter of maybe 5 seconds. Not sure what is involved with yours, but I simply get the nock pliers out, loosen, move, tighten.
I don't use a brass nocking point, either. But I'd still ask you why you wouldn't simply adjust your rest height. For me....(and I have to assume you don't shoot a D-loop)...."I'd" have to remove the servedin nock sets I have above and below my nocking point. Remove my D-loop. Tie in a new upper and lower nocking point....and tie on a new D-loop. I'd rather simply adjust my rest height if it's feasible to do so.
