Hi,
I’ve been practicing technique for a few months now, mostly adhering to the approach and methodologies presented by Troy.
Having practiced “conventionally” for many years prior to that, I can definitely tell the difference, and feel an incredible improvement in my technique, by my standards 
For me, the most effective advice, once internalized, was to adopt more of a trial and error approach instead of endless slow repetitions, which I had been doing for years prior.
This brings me to the challenge that I’m now tackling -
While my picking technique is improving, and my right hand is getting better,
I’m now at a state where what’s keeping me from becoming faster on some instances is non-right-hand problems.
For example, The mini triplet arpeggios in this lick:
Initially, I had obvious right hand problems, but that’s now fixed.
I can now prove to myself that my right hand is doing fine, because as long as I’m doing one position, I can execute the arpeggios sufficiently clean and consistent, by my standards.
During position shifts however, is where the problems start occurring.
I noted on one of Troy’s lesson, that actually, “it’s almost a cool problem to have”, and I can definitely relate to that! 
But, at the end of the day, I still can’t execute these sequences at the speed I would like to.
I’m quite sure there’s nothing mechanical that’s stopping me from succeeding.
Being left-handed, I’m confident in my mechanical ability to perform these position shifts.
So, in my mind, this translates to less tangible categories - muscle memory/synchronization - These kinds of things.
Also, I went over a few threads with similar subjects, and the consensus around them seems to be - nothing much to say about left hand technique, and that’s definitely my feeling as well!
This brings me to my dilemma -
Being convinced that I’m doing the correct thing mechanically, it seems like the logical conclusion is, unfortunately, many slow repetitions, metronome, and all these evil things.
But obviously, having witnessed how effective the trial and error approach is, I’d hate to go that path again.
What’s the recommended method to tackle these problems then ? How do I reconcile these kinds of challenges with the approach taught here ?
Thanks!
