hey guys got a quick question about my draw weight. right now i'm pullin 74# with my pse, andits a 65% letoff. the new dxt i will be buying is 80% letoff, soneedless to say the amount of weight i'm holding at full draw will be considerably less. i can pull 74# with no trouble at all, and so i was thinking about trying to tune my dxt at 80# just for a little extra speed and KE. will the extra weight really make that much of a differencein speed?
