I have a similar setup and also shoot the 7595 and 125 grain heads with great success. I would suggest you not cut all your arrow to 28" right away. Leave 3 of them a long, say 29", see how they fly. Play with point weight. You can always trim a bit more, you can never add it. When you have them dialed as far as point weight and arrow length, cut the rest. Just a thought.
