I refuse to believe that bad habits are permanent, but damn it is tedious trying to correct them!
I used a stylist for a while and saw significant improvement.
Back on topic, anyone here experimenting with the 'downward pick-slanting' technique discussed in the Cracking the Code videos? Been working on that here and my alternate picking is definitely improving.
The cheap version of this is to cut your standard .59 pick down so it has a point on it.
