Those are nice. I have taken Tommy Emanuel's advice and tossed my thin picks,(actually he said tio burn them.) and gone to a heavy pick. I do some finger picking, also. I like classical music, but can't do the crazy chords.
If you want to hear some amazing uke, and four string playing, google "Taimane Gardener", and your jaw will drop. She is quite the show woman. She is all over the stage, but she makes it look so effortless, and she is going like a bat out of hell, up and down the neck, and she is having a ball. I also like Hawaiian Slack Key guitar, and the South American style of guitar music, as well a Flamenco, and blues, and bluegrass, as well as the old acid music, of the sixties.
