Re: Todd Sucherman here!
I'm no foot technique expert. I just do what I do, and that most times I'm parallel with the footboard. Not heel up or down…just flat ghosting the board. But I can play both ways too depending on tempo and dynamics. Just like you can hit a drum more than one way, there's other ways depending of what you're trying to musically achieve. So I suppose it's good to have multiple strokes in your wheelhouse. Hope that helps.
