I like the CPT high-ever...
Upon further review, after one breezy day, there are remnants of the cover in my top along the high points along the side

which I thought was odd because I didn't think Tyvek would degrade (or degrade that quickly, easily).
Since this happened this week, I haven't had time to see if it will come off with a car wash (I do know it didn't blow off on the drive).
In use, the temp difference is nice and the CPT is easy to use. I just hope my ragtop cleans up.
