I know there are areas of my technique that could be improved (all of them actually just some need it more than others) but I've got
John Petrucci's Rock Discipline which covers multiple techniques and found it to be very good and wasn't sure if i should try some more specific DVD's. Any advice as well as your opinions would be really helpfull.
