I think when most people say "rough" for a woodie, that comes from the high-intensity vibration (the worst I ever experienced was probably a long time ago on a "3rd seat" of the Beast). If you sit "over a wheel," meaning the BACK of any car (not necessarily the back of the train, but the back of any car) there is alot more jerking and vibration. It all translates thru the wheels and car right up to your back (since your back is over the wheels in the back of a car).
The Timberwolf when it first opened was the greatest ride I rode up until that point. We got there at night, the ride had just opened a few weeks earlier. You couldn't see much of it in the dark, and we didn't know the layout. Got the back seat, as soon as it ripped down that first drop, YEEEEEWOW!
A few years later, they added ratcheting lap bars (yuck) and ugly, blocking headrests (yuck). They also put in at least one (one that I remember the last time I rode T-wolf in '98) trim brake. The second drop was also reprofiled to dampen some of the negative G's. So it isn't was it used to be. That first year it opened, I'm pretty sure it shot right to #1 on the coaster lists.
On a side note, it's way too bad they took out Zambezi Zinger, it was a great wild ride! It even had a couple spots with airtime, and a great long dark cool tunnel.

Ow! My lap bar IS down all the way.
