If you sight fish most of the time go for the Pro TC. Or just get the JM Thermal and use a black towel on the ceiling. I have the Pro TC and love it. Kept me sweatshirt warm on a 10 degree sunny day without the heater. The Jason Mitchell has a few upgrades though that are worth the extra money. I couldn't find any Jason Mitchell's when I got my Pro TC so I went with what was available. Both great houses but for the few extra bucks the JM is the better deal. The fabric on the JM is a bit heavier which makes it much more stable in windy conditions, not flapping as much as the non thermal fabric.
