Right hand position

[RuneMIkkelsen]

I've noticed some different ways to play slap bass.
Some play with their right arm in a 90 degrees angle to the strings. (Flea)
And others play with their right arm almost horizontal. (mark king, victor wooten)
I've been trying both ways. I think that I play fastest when doing 90 degrees, but I produce some more clean notes when doing it horizontal. And also 'double thumb'ing is easier when playing horizontally.
Have any of you given it some thoughts?

Well, whose a better slapper?
Victor Wooten... or Flea

Slap with your hand in a kinda thumbs up position.
Sure flea slap may be easier at first, but it is a worse technique.

I never found the Flea style easy. To me, it's hard to control which string you hit with your thumb playing that way. Stu Hamm's "Slap, Pop & Tap For The Bass" was my first real contact with the technique, and I found that hitting the strings with your thumb parallel to them is much easier. That video, combined with Tony Oppenheim's "Slap It!", helped me to build my slap skills. Mr. Oppenheim uses the "Flea approach", but it doesn't matter. The funk studies from that book are great for getting the proper "feel" of the slap style.
