I'm working on getting my right hand to move more fluidly; i currently keep my three fingers rested on my treble strings when playing rhythm, i have noticed when playing faster thrashy style stuff (180bpm+ 16th notes) those fingers tend to get fatigued or cause some strain.
When im not palm nutting, or playing faster leads (180bpm+ 16th notes) i close my fingers into a fist and am able to play more fluidly.
From your experience does resting your fingers on the strings a bad technique to have learned?
I don't think planting your fingers somewhere is a bad thing, in fact I recommended it. If that happens to be resting on stings your not using then I don't see it as a problem.
I think you right hand should be relaxed. Making a fist is not relaxed. I used to do this, I don't anymore and things have improved greatly.
