I got 12 years out of my previous supertop material.. I sold it to someone who is still using it. the current top is not 3 years old. never an issue except the rear support bows, but I stick a 1/4 x 1/2 bolt in the holes to support the support
If I had pics, I would post hard to explain. personally I would not get the sunride, I personally see the flip back as one more thing to break or leak, but that is just me.
