Using heat tape and cable

Anyone have any experience using heat tape and cable on the same thermostat? if so will the temps be about the same? I am looking to get another rack and i found one for a good price but it has heat tape. its a AP 3 high and i currently have an AP 6 high but It uses heat cable. should i just get another thermostat?

the wattage would be different giving different results.i would use another thermostat.have fun!

I agree if the entire setup is not excactly the same I would use a different thermostat for it.
