Hello, i've been perfecting my style of fingering a couple of months now, but i have 2 problems. first - when i play with my fingers, i have to pull the strings pretty hard to get my sound as loud as with a pick, which means that i have to push harder with my lefthanded finger(to get no fretbuzz). is it something i'm doing wrong or should i just train on my fingerstrength?! second - when i'm playing on higher strings, i hate playing with my fingers. i dont know why, probably cuz they're so thin which makes it feel innatural, and the mellow sound and then my LH thumb problem: i cant get used to putting my thumb right back behind my fingers and it hurts pretty fast too!
