Bounciness
FLASH, digging deeper into topic of bounciness we've probably got a number of factors at play these days. Although I cannot attest to traveling to dice tables in more than 6 states and 2 Canadian provinces (surely there are a few successful players that get around quite a bit more), it looks like there are two keys:
* layout material
* layout underlayment
The taughtness of a new felt/billiard cloth layout seems to produce more spring when the dice land from a steeper angle, especially if there is "yaw" (a term from the book, but a good description anyhow) in the dice. Worn felt loses some of this quality. An extreme opposite of worn felt is new microfiber...very springy, and I typically avoid it because it is tough for me to tame.
Underlayment of the felt plays a part. Remembering to the not-so-distant past of 12 years ago, the tables where I first started out at could handle high-arcing dice with a thud. Kinda like dropping them right onto plywood, which is probably what was right under the felt. Don't know if it was my limited range of play (could only get to a couple casinos at that time) or the "progress" of the last decade, but a fair amount of places seem to have
Now, I've never seen a table layout being changed (one box man told me they change it weekly, another says it's more like a month plus), but some do use something between the wood base and the layout material. A dealer told me cork (sounds odd to me) at one place, and another said foam. But FLASH, I would venture to say that a decent amount may not use anything (it seems all but the Nugget downtown LV don't).
Of course, I should have tempered all of this with the necessity for a low speed throw. Speed and force kill when trying to keep the cubes in check.
Enough out of me

If AP dice is a myth, then all of it is moot.
