I've got 2 pairs of 10x42's, they work really well for what I do. One is Swarovski the other Gold Ring Lepolds.
I have a pair of 7x50 Nikons that work well for daytime glassing from the Willys or camp. They are heavier than hell though so I don't like carrying them all day. I have a pair of 8x32 Bruntons that live in the glove box of my Willys, they're great for a quick look while you're out cruising around.
For me it was a compromise between super low light binoculars and something I could hold for long periods of time and have slung around my neck all day.
