Hey Dnk:
I just bought a Trykon and had the same thoughts as you. I'm 48 and my Ultratec was set at 63lbs. As theTrykonmay very well be the bow that they bury me with, I opted for the 50-60 lb limbs. The dealer set it up at 62 lbs and said that it was better to max out than be at a minimum with heavier limbs. Since Hoyts have a lifetime warranty I took him at his word. It shoots great (actually a bit faster than my Ultratec, even though it had anoverdraw and shorter arrows) and I can turn it down when I need to.
