I agree with Greg, no need for a STS...When I tested the Tribute, Allegiance, Trykon and Switchback,

I shot the Tribute using ACC 3-49's weighing in at 381...now mind you it was a 28" draw, not 30 and it was 70 lbs not 62 and was getting 291...take in consideration your draw is two inches longer with just 8 pounds less, you'll push the 290 mark easy. Let us know.
