I was thinking about building a snake rack at some point in time. I watched this youtube video and it was helpful, but I had some questions about it too.

1) he soldered the wires directly to the flexwatt and covered the ends with electrical wire. Is that a good idea?

2) Are you only supposed to have the one strip of flexwatt in the back. Do you just set it to the high temp and it tapers off to 80 in the front or are you supposed to have 2?

3) He only had one thermostat for the whole rack, but he had three series of flexwatt, was that a good idea or should he have had 3 thermostats?
