Here is one of my 65s.
After reading your comments I got this one which is 45@28. I draw to 27. I am lefty. I shot 30.5" bop 3555s with 175gr points, factory inserts. Three 5" shields. Factory shelf plate and rug. Brace is right at 8". 14 strand flemish B55 with Two Tracks's small scallops. GT factory nock fit is good to the serving, a light snap when the arrow is nocked. I draw to right at 27, but, I am a pull-thru shooter or reluctantly admit, a snap shooter. This is at 15 yards. The arrow impact is about 2"ish left of my point of aim. I am guessing 145gr points on these arrows would do this bow well. My arrow flight with this arrow/point weight is excellent. If I were to go hunting with this, I would build the strikepkate out a hair with the 175s or aim just right of where I wanted to hit and limit myself to a 15 yard or under shot.
The 65s are of the blocky era of Kodiak grips, but it did not cause me any problems. I gripped it with all fingers, not the "OK" sign grip. I much prefer the 70s grips on SKs.
As a lefty my arrows are left (weak), so as a righty yours should be capable of hitting right of your current setup (make them weaker). If everything you're trying isn't working, then you may have to consider it is possibly attributed to form - with that bow. Some bows I just can't shoot well, like my 62 Kodiak Magnum. That grip and my hand just do not get along. I love the bow, but it doesn't like my style of shooting.
Retirement is great when you can read a post and go outside to try something and then report back right away on a Thursday afternoon.....
