agreed,the ams quick retrieve bottle is the shit,we shoot alot below damns once the water heats up but we get the BIG dogs in local lakes where most shots are3-6'deep so we crank up our bows to 70+lbs,remove fletching on the arrows is a must,we found the stingerey arrow heads with long metal barbs rather than wire barbs work the best as guywhoshootsalot stated.Open water lake carp get huge in my area,to date I've stuck (2) over 50lbs,55' is my PBmost avg 10 to 20lbs,the bottle comes with 200lb test line and a break for reeling in and also saves your hand from rope burn on big fish.Buddy I shoot with nailed a giant years ago,we were shooting off a two person paddle boat,we had a couple on bigger over the years but this beast weighed in@ 85lbs,54"s long and 34" girth,we had the dnr come out as we thought it was a state record carp,however they shot us down because it was;nt caught hook-n-line,they did age the fish by the large silver dollar scales,few days later they called and said the fish was about 100years old.
I wouldn't mind taking a crack at these Big Head carp we see roaming the Detroit river,its said they get up to 100lbs.
PS~I'm old school and shoot instinctive and no release/sites,three fingers with a 3 finger leather archery glove.
