Any updates on the cooling function? I'm in TN also and am curious how cool the seat really feels on a humid 90+ degree day.
Thanks.
Looks a bit lower from the stock seat for sure. I'm sure it's comfy. Do you use a backrest?? I really like the look and it looks like a fairly good match to me by the picture. Enjoy. Looks great!! Stuart 
Sorry it's took so long to respond guys. Life has not let me ride until now.
I've not been able to measure the seat temp but I rode last weekend for about 3 hours and the seat was noticeably cool and seemed very comfortable. It got about 90* when I was on the way home and, though I was hot, the seat did seem to keep "my seat" cool and comfortable.
It does sit me lower for sure. I had to buy a 2" shorter windshield so I could see over it properly. With my original heated hammock, I couldn't get both feet flat on the ground but with the new hammock I can get both feet flat and my knees are actually bent some.
I am using the stock backrest. Like Stu said, the seat isn't an exact match but I don't think it looks bad at all.
I'm taking the Road Glide to Maggie Valley for our GTG on Sunday and I hope to get some good rides in all week so I will have a better idea of seat comfort on an all day ride. Ill try to be better about getting you an update once I've done some all day rides.
I hope this helps. Let me know if I can do anything else.
