So sad, but so true! :pound: I've been on the other end of dealing with wheel issues on a coaster, and it can be difficult to find the right material blend. Add in weather factors (they have special winter wheels for the cooler months/days) and it gets worse. With the kind of extreme weather changes the area can see, it can really complicate wheel performance, and it isn't as simple as taking the wheel blend from Dragons or Hulk and slapping that on Rockit. I would think a fairly balanced nylon/poly-u blend would be a good catch-all wheel in Florida weather, but obviously not for Rockit. Of course, some coasters just blow out wheels like they're a nickel slot jackpot. Nothing to do but change a wheel or two every day. This also. Sometimes I love getting into the details of ride systems. It can be a lot of fun.
