You'll need to shoot weight head that shoots with your setup. 25 grain usually will not make a big difference.

Onthe stinger - I have used them for the past three seasons (150 grainwith bleeders)and have taken three deer with them. The blood trails were very good. The only problem that I had with them was penetration. I didn't seem to get passthroughs with them. I even had to put a finishing shot into one deer and didn't get a passthough at five yards. I'm sure if I remove the bleeders, it would help.

But, I wouldn't advise against them.And they are very sharp out of the package.
