If you're going 'cheap/used' I would opt for the greater loft versions e.g. 11.5 - 12.0 degrees if you can find one. Adjustable would be even better but I agree that getting fitted is the way forward. I went to American Golf and spent half an hour with one of their guys on their machines. This isn't the best option I'm sure but suited me as I had a bit of an idea what I wanted beforehand and just needed to check the numbers generated.
