I don't really know the Heed very well, but does it work for both your current motor and the 24V motor with the ttpsu? If it does, then you could use it for now and if your orig motor were to crap out, replace it with the 24v/ttpsu combo at that time. If it doesn't work for both, I'd go for the 24V/TTPSU for now and depending on your results look for a PS in the future. (I just ordered a Swagman SE for my RP6, looking forward to when it arrives.
