kk awesome so basically there's no right or wrong , or good or bad technique, it realyl depends on the context of the song and how the powerchords are being used.

So if it's a riff consisting only of powerchords then i'd prolly bar with my first and pinky (or my first and ring for higher riffs) but if its a powerchord that's a part of a more complex riff then i might use my ring and pinky so i can improvise with it, I just find it less accurate when i'm sliding powerchords around.
