you need to walkback tune. your arrows should hit the same left and right no matter how far...also work on form and grip. errors are magnified at longer ranges...not following through is a big problem...but it could simply be the tune...shouldnt have to move pins left or right...move the whole sight for that.
good luck...
I agree with the above statement.
As far as recommending a sight I would go with any thing that is a tool-less design with a micro adjust feature. I can't stand fumbling with tools and then there is the "oops to far go back a little isnt't that where it was before" factor thats is eliminated with micro adjust feature.
