Thank you so much everyone for all your responses. I've had a good look at Evans and Duo,and their selections both look great. I've just ordered a pair from Evans, as they're a bit more in my price range at the moment, but if they're no good I think I'll wait a while and invest in a pair from Duo.
I'm trying not to get too excited, but I really hope they fit. I'll find out in a couple of days when they arrive, I'll let you all know.

Thanks again for all your advice, it's so nice to know I'm not alone.
