For grins, I'll call them tomorrow to see what the pricing is like today. I see Keyston is carrying it but if a timely delivery is needed, you'll pay big time. I think it's a combination of weight and the fact that Weathermax has a nylon windbreaker like feel to it and slides easily on itself that makes it more agreeable on larger projects. It's still 8.0 oz/sq.yard vs 9.0 oz no matter how you slice it. A Sunbrella cover that uses 32 yards of material would weigh just 2 pounds more than the Weathermax. The OP in this thread was looking to replace a cockpit cover so the difference in weight would likely have been less weight than the keys and change in his pocket. Totally agree with the rest. Color availability, material size play a big part in what we do too.
Keyston is terrible. They would tell me they have my yardage in stock then right before it shipped they would call me and say it was out of stock. My other suppliers charge me flat rate well under 20.00 to ship (I order a lot of canvas for over 30yrs.). I get it mostly a day or two, three at the most.
As far as handling I will put it another way to better explain what I meant. The difference in handling is like loading a pick up truck bed with 50lb bags of sand and 50lb pounds of feathers. They both weigh the same but the sand bags will be harder to handle. Another thing about WeatherMax is it has no stretch. Due to the low profile of most cockpit covers Sunbrella often stretches in a couple of years and pockets water mostly in the rear corners. Sunbrella stretch is mostly in the fill (from side to side). The warp (fibers going down the roll) has much less stretch. This needs to be concidered along with pole height, number of poles, and position of poles, when designing Sunbrella covers.

Sunbrella is much better for most application. There is a reason most of the experts use it and it's used almost exclusively on higher end boats. An exception might be if you literally can't have one drop of water on board. Sunbrella will let a few drops in over time, but it's insignificant. The other 2 exceptions are price and superior abrasion resistance.
To me, the better breathing alone makes Sunbrealla worth it (far less milder, mold, scum, etc), not to mention the feel, longevity, look, etc.
