When I had my first non-programmable shunt put in, I went on every roller coaster in the midwest, but I'm not so sure about programmable ones. I'd say start out on a slow coasters like one of the kiddie roller coasters and then go from there. Let me know what happens, cause within the next month or two I'm going to be having a shunt revision and trying to decide if I should go the programmable route this time.
