For anyone who's notated any kind of two hand tapping pieces, how do you do it? Do you put it on two staves, just like a piano, or stick all the notes on one stave as in normal bass notation?

I've been working on some easy piano pieces that I rearranged for bass, and I put it all on one stave, which I find much easier to think about and read, but I was just curious if there's a "standard" way of doing this.

Cheers
