I voted for 10's. When I started it was 9s, even 8s, but I think that I was influenced by all these heroes of mine saying that lighter gauges are for wimps and that you have to bleed for your art.
Don't believe that now, and I do think that you can get great tones from 9s or even 8s - it's more about pick attack and amp settings, in my humble opinion.
