Wow..two stacks of ten simultaneously...that's ridiculous.

I'm almost up to being able to do 8 and 8, but in my right hand only. You're right though that it helps to pass the time when you're doing a lot of folding. The only drawback I think is that it is more likely to clue people in to the fact that you're a good player when you first sit down at a table. So I tend to refrain from shuffling during the first couple of orbits in the hope that I'll pick up a big hand and the tight players will think I'm getting overaggressive with a marginal hand.

Also I find that if I'm shuffling for a few hours my hand starts to get a bit sore. Almost like the onset of carpel tunnel or something. I wonder if that's a problem for B&M rounders who shuffle chips for hours every day.
