Dave,
I would be interested to hear exactly what they did to the string to add that extra .5 inch of draw without throwing off the timing of the cam. As for the string loop...truthfully, it doesn't add to your draw length but rather just changes your anchor point.
In any case I am glad to see another big guy shooting a little bow.

The Triumph is an excellent choice in my opinion. I also like the specs of the Raptor though its overall design is a bit more reminiscient of the Mathews FX/Jennings Rackmaster/PSE T-bolt rather than any of the newer parallel limb designs. Again, just in my opinion.
