Greywolf(screenname) has a very similar setup to the Trykon XL and I have a Trykon XL with the same setup with the addition of a half inch of draw length and I pull 70#...He recommended the 125 grain tip for a 60ish # pull setup. At 70# I shoot the Axis ST 340's pretty straight even in moderate wind conditions. Through the chrono I picked up 17 fps going from 62 to 70#. What im getting at is...I would either crank the draw weight up, if you are able to shoot well with the heavier draw, or maybe the better option would be to try the 125 grain tip. At a reasonable distance the 125's will almost always be a better way to go.
