Man, deer have been killed by many two bladed arrow heads, yours are made of razor sharp metal, some are made of flint or stone. Do your thing, and if that head isn't good enough do like the first Americans and club them to death, any way you get meat is fair. [legally]

I would also actuaally suggest the Magnus heads. I shoot them first hand, and I dont ever plan on switching from them...I also only shoot 85 grain heads, I got a passthrough on a deer at 41 yards this year, quartering to. These heads are scary sharp. and fly with your field points. I personally would go with the buzzcuts in 4 blade as well...Not only that...if one breaks, send it back to them, and they will send you a brand new head, they have a lifetime guaruntee!!!
The one other deer i got with them this year, was a doe at 12 yards, ever soo slightly quartering too...punched one shoulder, and stuck 6 inches in the ground behind her...Both my deer so far have gone less than 40 yards...
