I've used Shurco and Thunder on my hoppers, no complaints either way Shurco seemed to roll a bit faster but I don't have to set the stops on my Thunder. During very high winds the Shurco just did its thing with the help of the hurricane straps, haven't used the Thunder in similar conditions
Appreciate the answer. there's so much out there, cheap stuff, expensive, I don't know if you get what you pay for of what the difference is. thanks for the tip.
