I can understand being concerned about the 85's, but I think I would be looking at the cutting diameter. What did the FOC calculator say if you went to the 100 gr. heads? Was thee much difference? I'm making the switch this year to either the Slick Tricks or Sonics, haven't decided yet, but definitely the 100's for me. I'm hoping for a little easier time in tuning. They kill elk with mechanicals, which I don't think I would personally use, but I can't see where the 85's wouldn't do the trick.

NODOG,
I spent hours with the GT's and eventually ended up switching back to the 2413 aluminums 5 days before leaving for elk camp. I tried every trick in the book to get the GT's to hit the same spot, and I consider myself to be a fair hand at tuning. I'll be trying it again this year with a new BH, and am hoping that by using one of the smaller styles it will work better. I had followed all the basics of shooting paper and had bullet holes, the BH's were about 6" right so I went on to rest adjustments to group them up. THe closest I could ever get was 2" at 20 yds. Not perfect, not acceptable. I'll be trying 5575's with smaller BH's 'cause I have 3 dozen cut and ready, and some 7595's that I picked up from a friend. We'll see.
