I used 2 blade cut on contact myself. I use the carbon express like driver 150gr broadhead. Shoots like a laser and leaves big holes with lots of blood.
I've since went from 450gr setup to a 660gr setup and I really like how the bow reacts. The shower arrow makes up for the heavy hits. Sunset your looking for whitetail I'd keep the lighter arrows for the fastest possible arrow without losing too much arrow weight. Whitey's can be jumpy
Happy hunting.
