I do not have any hands on experience with Hawke. Where is Hawke Frontier APO made? Tract Toric is made in Japan. Might be something to consider.Have you any familiarity with the Hawke Frontier APO 10x42? They seem similarly specced to the Tract. How does the Schott HT glass of the Tract compare to the APO of the Hawke? Other similarities/differences?
If I had to guess I'd say Tract Toric will perform better as it is in the same class as say Zeiss Conquest HD.
Amazon sells both the Toric and Frontier. Could you buy them BOTH on Amazon, do a comparison, then return the one you don't want?
