Indeed but I can't afford that option! I've been birding in Iceland this week with my wife's 8x30s as my 10x42s are back with Swarovski at the moment and I don't think I have missed the extra power, and have definitely enjoyed the more stable view in the wind. I'm going to check out the 8.5s as possibly the best compromise.
Thanks for all the advice everyone.
