A few pounds on the draw weight makes very little difference on the output velocity so shoot what is comfortable. On my Mathews Ultra II one pound makes 1 fps difference. At least from 60-65 pounds. I also use a peep and tube for the reliability and never having to check my peep before drawing. Not a big difference for deer from a stand, but huge when spot and stalking IMO. I lost no velocity with the new tube peep, but I did also go to a upgraded string, so maybe they cancelled each other out.
