I used the P-110 probes described at: http://www.aircraftspruce.com/catalog/inpages/eip110egttit.php because I didn't know about the Micro-1000 probes at the time. I haven't heard of any problems with the probes because of the rotary exhaust. Any of them should handle the temperature OK if the pulses don't get them.
