What’s the roughest coaster you ridden?

It's a tossup and both coasters are now gone. Dorney's Hercules - aka HurtMyKnees and SF GrAdv's Viper (or as I called it, Diaper). Then you have coasters which had multiple trains and some were rougher than others - a good example was Sf GrAdv's Scream Machine. Others that shook me up were the former Wildcat at Hershey which is an RMC hybrid now. That ride was only rideable in the first 3 rows (for me). I rode it once in the back and had to sit on a bench for 15 minutes just to get my bearings back.

Jersey Joe

Infusion at Blackpool Pleasure Beach, the only ride I've been on that I'll never do again

King Solomon's Mines (wooden wild mouse) at Pleasureland, Southport. The Blackpool mouse was good. This, unfortunately, was not.

Invertigo. I haven't ridden it more than once or twice, so I guess I should try to give it a second chance soon.

I've always wanted to get on the Invertigo slide

oh, I'm talking the Vekoma at Kings Island. I'm personally not a water park guy but that slide would be cool!
