My $.02………..I have the 10x42s and really like them. I got them before the 32s came out and planned to make the 42s my general purpose bunos. However, if I had to buy again, I would get 32s (probably the 8x).I typically take 2 binos on hunts and feel the smaller set would make for a more useful setup combined with 15xs. Now, if I was only going to have one bino, it would be the 42s.
I prefer the handiness of the smaller 32s, when making a final stalk and saving the larger diameters for spotting.
