I use a similar bass/arm weight technique when I play and it works well. I can always tell when I'm doing it wrong too because a song like Sha Na Na's version of "rock and roll is here to stay" is easy if I do it right and I can't finish it if I'm doing it wrong
*the Sha Na Na line is much more fun than the original btw
