I would opt for a lighter arrow, but leave the weight alone if you're comfortable with it. More weight won't necessarily give you more speed as you have to shoot a heavier arrow for the weight. At 65# you should be able to shave as much as 125gr off the arrow weight and gain a bit more than 20fps. This should flatten your trajectory considerably. You won't see much POI change at 20 yards, but your pin gap will close up. With a speed of about 260fps you should be able to sight in a single pin for about 25 yards and shoot almost any deer between 5 and 30 yards with a center-chest hold. It makes guessing yardage easier because you don't have to. Just aim and shoot. You should notice about a 3" drop from 25 to 30 yards. You'll be about 2" high at 20. Not enough to worry about.
