Never play the "crazy shit", they're just terrible bets. If you really want more action, lay the 6 and 8 when the point is something else. Not as good a bet as pass line + odds, but at least you're not giving away your money. Personally, when I want action, I keep throwing come bets up and putting full odds on. You'll win a ton or go broke it a hurry, but it's a rush and as close to neutral EV as you can get from a casino game.

Also, a hot shooter is just lucky and there's nothing else to it. The dice have no memory. I know there are a few people out there who can set dice, but I guarantee they don't play at the $5 and under tables.
