While Summit Plummet is one of the craziest drop slides I have been on, I still had no second thoughts once I was sitting in the pool at the top of the "ski lift" during my first plummet. Thinking back to it now, the one thing that was the biggest pain after that ride was my backside. The amount of force that was generated from the radius out was insane. I can remember after riding how awesome it was but how much I hurt after and not so much how crazy it was.
As for Verruckt, I could see there being an extensive amount of force during the pull out before entering the upwards portion of the second hill that is comparable to SP. I really hope the toboggan seats are padded well. As for the ride itself, it looks awesome and can't wait to hear more reviews about it.
