Thanks for the link! This is super great for me to go back and review now that I’m a little further along and have forgotten all about it. 
I’m realizing how dicey the fit of my thumb pics has been and I’m wondering if that’s why I’ve had trouble building speed. They kind of all sit too close to the knuckle and I think it makes me move my thumb more than I should have to with a proper fit.
i’m realizing the only thing I have that comes close to properly fitting is a slick pick. I did order a small blue chip and I’m gonna see if that fits straight out of the container, if so, I think that’s my best solution. Or just stick with slick picks.
