Hi t.walker.12,

It's always good to train your pinky. Yeah, power chords might be easy to play with either combination of fingers like index + pinky, or index + ring barre.

I think it's important that you're hitting that third note in a power chord triad, whether you do this with your pinky, or using your ring finger to create a barre, it works. I've seen a lot of artists do it both ways.

I suggest learning to play with a pinky because it will give you a ton of versatility down the road, it also might help with the clarity of the chord, since you won't be accidentally pressing down on a bunch of other strings and notes like you might do with a barre.

Always train the pinky!

Those are my thoughts. Good luck!
