Anyone with experience with these... what type of heating should I get. Back heat or belly heat? I heard they use back heat and they "say" it's better than belly heat. Also, they offer 80 watt flexwatt and recommend it for rooms that may be below 74 degrees. During the winter, it will definitely be in the 70s from time to time.

Is it MANDATORY that I get the 80 watt, or can I get the 40 watt standard and just rely on my helix backed up by a ranco. I'm not entirely sure.

Thanks for the click guys.
