Years ago, I remember Troy and Cracking the Code being spoken about every now and then on the forum. That, mind you, was before anything was even out. Now, there is a ton of stuff available, but I don't see it mentioned very much. The reason is probably that is quite pricey, but still: has anybody tried any of it? After all of these years my speed picking still has some way to go to become consistently at top speed, and this seemed very promising.
