I found this neat read...pretty informative.

Again - I want to say I'm sure there's a reason some aftermarket builders use solid shafts...I've just never spent any time to look up why.  |
If its balanced and aligned with precision, the centripetal force that normally causes the "wobble" shouldn't really be an issue. I don't know how much focus they put on balancing a drive shaft though. Probably little to none.
