Well, I am still trying to pick out the right cover.
I saw one chart where they are claiming that clear is way better than black(+blue) or silver(+blue), but I am not sure about trusting one source. Other places seem to charge less for clear compared to black or silver. Then there's gold(+blue).
Cost-wise I am okay with any of them, and want what's best for heat retention and production (especially production). Gold seems best to me, but maybe that's just what they want me to think.
Also, I was planning to get a 12 mil so it was more managable, but would love to buy a 16 mil for durability and heat production. 16 mil can't be handled by 1 average strength person? I do have a reel. It's older and I suppose it's not as good as most of the ones for sale now.
Oh yeah, there was the idea of cutting the thing in half, but then it couldn't be reeled up. And supposedly if your entire cover is in contact with the water's surface (no edges sticking up out of the water), it won't blow away or anything... but if it were cut in half maybe it would?
