I suggest with your set up using 100 gr Slick Trick Viper Trick. These BHs fly true, have solid ferrules and their profile will give you good penetration. I would hesitate using a big cut mechanical with your set up. Especially if hunting from a treestand. You may get decent pentration but you may not get a pass thru leaving the possibility of a less than good blood trail. Even though you will have a lot of internal damage.
