I can think of two instances where people have been hurt by hitting on the wheels hard and compressing against thier seat. Skinny in St. George, and DSI in SuperCrawl III (were either using aluminum seats? I know Skinny wasn't?). Are there a lot more occasions that go unreported, or is the danger being inflated. There are a lot of people using these seats, and I don't hear about people getting hurt. I would also be surprised if the aluminum seats have much (if any) more give than the plastic seats that i've been using the last couple years (and many others are using them too). I'm listening to you guys, I'm just not convinced yet. Putting in a couple of cushy suspension seats is going to massively alter my buggy plans, and I'm not willing to do it unless I really think there is a problem with the aluminum seats. Is anyone using them and happy with them?
