And as for the 25ers, I'm not sure what "regularly" means, but they make their share. They aren't really that rare. In fact, in my weekend rounds, I'd say I see at least two "bombs" over the two rounds, and that's from crummy players.
I can see why the other poster got the impression though. When watching TV, they always show those long ones, it makes for good viewing, but it can be misleading.
