The Leica has a huge amount of parallax forgiveness. Eye box is better on the Leica as well. All in all it's a pretty nice joy to get behind it. Shot it today on the 6GT and I'm going to keep it. The open circle reticle is almost impossible to see at < 16x, but I find that the cross hairs come down to an open center anyway, that I can always open center hit things within .1 mils which is fine for any sort of speed shooting. (It is also almost $1000 more than the Tract though)Would you order the optics the same way you listed them? How do the eyebox and parallax forgiveness compare on the Tract and Leica?
For competitions with heavy holdovers, I personally am loving the Razor HD AMG the best, the holdover lines are nice and thick and are usable at 10x. To use holdvers in the Tract (under time/duress), I'd need to be at 15x, and 18x for the Leica.
