. . .I weighed 3-LS 2 Lite arrows and they averaged 298.5 grains without heads. I then weighed 3- Lightning Strike MX arrows and they averaged out at 333.3 grains for a difference of about 34.8 grains. . . .When I got my TR I called Horton and asked if I could shoot the lites in it and they said it would not hurt the bow but they really would not recommend it anyway.
Thanks. You just figured out the mystery for me. Well, off I go to get 125 gr broadheads and practice points. I only shoot LS2 arrows. I need some broadhead replacements anyways. I couldn't understand why my new Lumi-Zone scope was telling me my arrows were going about 325FPS when I was shooting aluminum arrows on a 315fps xbow!
