Betting structures in different forms of poker

[slapdash]

While I was being annihilated in the Hendon Mob HORSE tournament yesterday, I was pondering on why different forms of poker have different traditional betting structures. In Razz, it's not that uncommon that you can know you have the best hand at the moment. E.g., you could have 532 when nobody else has an upcard below 6. But on the other hand, when this happens, you probably have quite a large chance of losing by the end of the hand (at least compared to the times in Hold'em when you know you have the best hand). So it would be much more attractive to be able to make a big bet to try to win the pot right there, and this would make it rather boring. Presumably this is one reason you never see no-limit or pot-limit razz (or do you?). The same principle probably applies to other stud games: compared to hold'em, when you're ahead (at least early in the hand) you're more vulnerable to being outdrawn, so a no-limit structure would attract too many big bets to close down the hand. Are any stud games often played no-limit? Or pot-limit? And does anybody have other reasons why certain games tend to use certain betting structures?
