150 pound bench press? I hope that's a typo! My senior year in high school I shot a Jennings Super Sonic XL at 94#. I didn't gain anything. Now I look back and see how stupid it was, that was only 6 years ago. That settup did 260 feet per second with a 2512 and a 100 grain glue in. Now with todays bows, I can get the same speed with only 63#. Save your shoulder for more important things, like high school baseball!!
