Bailsuk, thanks.
i shoot a bowtec 82nd airborn, she's so fast i have to go with as bright of fletching and tight of rotation just so i can see her go.
then its down range at least 7 yards before my eye can catch up.
then to even shoot just a little bit quicker I shoot with a drop away rest that allowes me to shorten my shaft about 4"
this takes off about 3 grams.
she's zipping out at around 342 ft per sec.
For ever i shot feathers but they sing to loud with that much speed, so now only plastic vains.
good luck with you hunting this season.
