I have really ridden only one "true" Dinn/Summers woodie and that would be "Mean Streak," which is one of my personal favorites. I was actually supposed be a ride operator on it for this past season, but things happened and I couldn't take the job. Yes, it is very rough, but so is the number one woodie right now: "The Voyage." When I took my one ride on it, I was BEAT. I must say that I enjoyed "The Legend' much more.
Also, "The Beast" technically is a Dinn woodie. It's an epic woodie that has had some extra braking over these past years, which I thought this year was a bit lighter than a few years ago.
Summers was a structural engineer who worked on MANY roller coasters (indirectly brought up by a mention to his work on "Thunder Road"). If we go down this road, we can also bring up Kennywood's "Steel Phantom," as Summers designed much of the structure. Of course this coaster was a good ride (except for that horrid 80 mph turn) and has been improved wonderfully as "Phantom's Revenge."
