Wow. Sounds great.
My two cents I go to about 6:15. Trying to keep tempo, i have some energy but fingers not quite doing what brain is telling them to do...
Good job! I have basically the same problem. I have developed a little bit of arthritis in my right wrist. Every now and then it responds with, "Nope, aint' doin' that!" Left hand is fine. I was never very good at hammer-ons and pull-offs, so I tended to pick everything. This has forced me to work on them. I'm still not very strong at them, but it's a whole lot better than a year or so ago.
