Technically Octave glissandons are usually done descending in the Right hand, and ascending in the Left due to the way you can curve your thumb to drag it. I can do octave glissandos in both hands, but as I said - RH down, LH up.
I guess your new program is a breath of fresh air after such detailed work on your last one!
What about the pinkie... how do you drag it?
I can do a 7th gliss, and if you hit a single octave at the top and then come down fast enough, it'll pass. Never needed to play one in public, mind.
