Sorry, yet another one of these topics, but I'd love some thoughts specific to my situation. I'm pretty certain I'll only need one heat source, plus would like to use my single probe Herpstat. However I've continuously gone back and forth on which to get. Some details:

- 4x2x16" PVC enclosure
- target temps: 78-80f ambient (for BCI)
- room temp is usually around 75f
- I crank up the heat in the winter
- currently I'm using a 28qt tub with a Zoomed heat pad, and can't quite hold my target temps 24/7 without the hot spot overheating (does PVC hold heat better?). it does get warm enough in sunny afternoons, but is often a few degrees short
- I'm going for a more naturalistic enclosure with branches, fake plants and natural substrate

So, would you suggest an RHP or Flexwatt? I'll of course spend extra for the RHP if I have to, but I just want to make sure it's the better option?
