I am planning on buying a pair of Vortex Razor HD binos, I'm looking for a little input. the 10x50s are about an inch taller, and 5 ounces heavier than the 42s, just wondering if the 50 vs the 42 is worth the extra weight, bulk.? I have the KUIU bino system, and like it a lot, and I'm a little worried about getting the 50s in and out of it easy enough.. any thoughts would be appreciated.
