It was awesome this year being part of this team, we gave it a good run!
Now the arrow build! First your going to want to build a few different arrows to play with before tuning, as I'm sure you know. Not trying to insult your intelligence!
Once you figure out what weight works best for you, build a simple 3' x 3' square out of 1"x, get a cheap paper towel holder, like the ones that have two tabs that slide into the roll. Cut it in half and space it to fit wrapping paper rolls. When you unroll the paper, do it so the color side is facing the target which will leave a clean white face for you to paper tune through.
Back to arrows, You can piece together a heavy enough arrow using what you have (with a little extra weights) but it will take a little playing around. I personally shoot aluminum 30" easton game getter's with a 50gr brass weight on the back of the aluminum insert with 125gr magnus stingers.
Turkeys, that's my game right there! I enjoy deer hunting but I'm obsessed with turkeys. My wife would say I'm obsessed with both but that her story. Although, this year I may have a little less time to get after them with the baby boy coming in april, so I'll probably just focus on getting my daughter her second bird this year.
Good luck, god bless.
