Steel Force Phatheads, 100 grain. I switched to them last year and I really like them. They're a cut-on-contact head, with a mean .080" thick blade... Very tough, very sharp, and since they have a stout profile they are as accurate as any other head I've tried. I only shot one deer last year, but she only made it 30 yds before piling up. I don't know if they're any better than some of the other fixed-blade heads, but the fact that the blades are literally twice as thick as all the others out there really gives me confidence in them.
