Here is my set up if it helps 03 Patriot Dually at 74-75 pounds beman ics 400 arrows 26 3/4 inches 27.5 draw length chronographed at 286 before I went to a tru-peep and had rubber tubing so I am guessing about 290 now. I plan on using 100 grain tips giving me a total weight around 405. this equals about 74 pound ke I think.
