the eye cups don't bother me... it was notable at first because it was different, but once i got used to them, it wasn't ever a thought, and they became very comfortable to sit behind.... it's always tough to tell what quirks will bother people and what won't, but after considerable time behind those binos, i wouldn't change the eye cups... i like them, there was a brief getting used to.... there was a brief getting used to with my NL pures too, they are different, and it took a few days behind them before i could truly appreciate them.
