I can update that my blanket has not seen any wear, the wastgate arm has not been binding at all. Drivabikity has not been impacted.
The blanket is holding up surprisingly well for its low price point. I daily my Sky, so it sees a lot of mileage.
While I plan to purchase the K04 blanket that KG posted about, that won't happen until I have completed my move to the Minneapolis/St Paul area. All projects for the sky are on hold temporarily.
