I think you'll be fine with either of the blades that you mentioned. Personally I'll be using the stinger 150 grain head. If you are concerned with your choices, then maybe just remove the bleeders on the stinger.
I didn't know Stingers came in a 150 option.
As far as removing the bleeders, I know a 2 blade will maximize penetration potential, but at the cost of hole creation.
