Hi,
well, now that was a somber review... this sounds like you might get a case of upgradeditis soon, so if you have not yet committed to keep the Ultravids, I strongly recommend to try to get a look through a Zeiss FL 8x32 and a Nikon EDG II 8x32.
Both will be close to perfection optically and address your problems with CA and Coma - the EDG will also have the best field flattening money can buy. The Zeiss on the other hand is also small and light...
