Sorry dude, I didn't your question until just now. The probe is holding up very well. Clean it each time with a damp wash cloth after use, and it still looks good. The only problem you will have is that the diameter of the armor is over 1/8", which means you won't be able to run the thing through the door. I think this is a good thing though as it forces you to run the probe somewhere where it won't get damaged. On my chargriller, there are so many holes already in the thing, there's no problem finding a place to run it. On my drum, I drilled a 1" dia whole at grate level and inserted a 3/4" pipe nipple to run all of my probes through.
You will be pleased with the probe. Also keep in mind in the future that ThermoWorks sells a thermocouple cable extender. I have several of these. You can daisy chain them to about whatever length you want with no calibration issues. When I don't hook the smoker up to the control program, I add the extenders and run the cables through the window. That way I can check the temperature using the Thermapen without having to drag my lazy butt off the couch.
Keep us updated on the MTC, and enjoy the Jelly Bellys (You'll find out what I'm talking about). Those ThermoWorks chaps are top notch!
