Jools Hagons are great, they don't charge you if the wheel won't straighten. When WJB had his 'little' off at Donington last year the front marchesini on the TZ was bent badly enough to break the tyre bead-they straightened it. Dam tough those forged marchesini's. Give them a go mate-you have nothing to lose.
Have you asked the seller? Because a lot of people say they don't do it, and when you ask it is no problem. Else, if you can't work it out, just let me know. Perhaps I can help.
