Starve your Fear, Feed your Dream!
I'm working on the Evan Marshall pieces in the OP. I think it'll take at least a couple of months to get it down clean, but I think it'd be worth it.
It was the same way with pami and piami fingerstyle tremolo.
I have been doing PIMA for years, in fact I started playing that way so it is natural. Flatpicking isn't natural and has been a battle. It is what happens when you play multiple styles and trying to be competent in all. Growth slows because dedication, concentration and focus is not stuck to the same style.
I have been messing with the large sized Mando plectrums - also very different.
