The cutting diameter on the 85's which I used extensively last year is about 1/64th shy of an inch. The cutting diameter of the standard blades and the magnum blades is just about spot on. TheSlick Trick85s as well as the standard 100sprovide field point accuracy out to 45 yards at least. The Magnums are very close and farmore tighter than the Thunderheads or Muzzys or my previous favorite the Rocky ti100. Just shoot a group with the Thunderheads and the Standard blades out at 45 yards and you'll see right off. Now if you're shooting a faster setup, it'll show up at any distance.

For myself I prefer the 100 with the standard blades over the 85's because the cutting surface is a little longer on the 100s.

I have a buddy and he went to carbons and got the right cam and setup his bow rightand really increased the speed of his setup. A die hard Thunderhead shooter, as we all were. Well he can't group the Thunderheads now to save his life. Yet with field points he's tight. With the Slick Tricks with the standard blades, out of his setup, there is no difference in group size at 20 compared to field points.

Right at the moment I think the Slick Trick 100s and 125s with the standard blades are the overall best fixed heads out there, especially if you're shooting a faster setup.
