Do they have lap bars now too? If not, I wonder what the difference is (physics wise or behavior wise) between CA and FL.
DL's version is the original, with 'single' style logs, and no lap bars.
The ride experience is quite different then WDW's later version of the Attraction.
I find the primary differences, not including the different show elements, is the speed.
You pass the show scenes very quickly when compared to WDW's version, and the final drop is much faster...or at least it sure feels like it to me.
Might just be the smaller logs, but you rocket down that incline like a bullet at DL. I don't get that sensation at WDW.
At WDW, the 'double' style logs don't make it seem as fast, and you pass the show scenes at a much more leisurely pace.
This is nice, because the detailing and scale is visually superior to the DL Original and the slower speed allows you to have more time to enjoy it.
I love both versions, though the Original is a personal joy for how 'rough' it is in comparison to it's FL counterpart.
WDW's has the more fleshed out show scenes and a more elaborate treatment inside then DL's.
So if you want to see a great interior show, WDW's is 'it'.
If you want to experience the Original, and have a speedier ride, DL's is 'it'.
