I'm a bassist, but I'm playing guitar in a band - [url="http://www.junkyarddogslondon.co.uk"]www.junkyarddogslondon.co.uk[/url] if you're interested - point is, when I was just a guitarist, the strings I used were 10's and I remember thinking they were [b]thick[/b].
Having been a bassist I now use 11's. I'd use 12's but I often bend the G string and haven't found a pack that doesn't have a wound G.
10's feel so sloppy, and 9's are just unplayable!
