What banjo style did you play before trying minstrel style?
I tried Scruggs-style but just couldn't get my fingers going that fast. I learned the basic bum-ditty strum and some frailing.
If you play clawhammer, do you have any difficulty going between clawhammer and stroke style?
I've had some difficulty learning to use my thumb more when I want to hit the string with the nail of my middle finger. It does seem that the 3rd and 4th strings sound clearer if you hit them with your thumb instead of your finger.
