The question was brought up about which bow would perform better or would there be any difference in speeds between them. So we set out to find out the truth. Today I tested 2 Mathews Switchback XTs. Here are the specs... Test Bow #1 70# peak weight, set at 60.21 pounds 29" draw length Specialty Super ball peep installed String loop installed Axle-to-Axle as tested 31" Brace height as tested 7-9/16" Whisker Biscuit rest Test Bow #2 60# peak weight, set at 60.05 pounds 29" draw length Specialty Super ball peep installed String loop installed Axle-to-Axle as tested 30-15/16" Brace Height as tested 7.5" Whisker Biscuit rest The arrow used was an Axis 400 with blazer vanes that weighed 400 grains. We took multiple shots with bow bows to get an average and the results are as follows. Bow #1, 70# set at 60# shot 257fps Bow #2, 60# set at 60# shot 260fps. So there you have it, there is a 3 fps difference in the two bows. The peaked bow was faster. The 60# was actually turned down slightly because with the limbs bottomed out it was just over 62 pounds.
