I think it was metioned already about metric. I agree. A program of this caliber should have the option to use metric. Other than that its not bad. It looks cool and incorporates alot of neat ideas. I had used crack shot I think thats what it was called, and this one has vastly improved over it. To be blunt, the crack shot version was useful and a great idea yet lacked functionality. The reticle optimizer in this version is a dream. It does take out all the guess work. I dont know that I personaly have a need for some of the other features like the barrel life alylizer and putting pictuers in it I most likely wouldnt do and such but as far as the exterior ballistics aspect of it I would give it an A-. I would give it an A+ if it also used metric. Just curious, why do certain fields change colors depending on if something is entered in it or differant colors are used for others???
