Officially we have tested against no other tools in our range. Any that do work do so as a matter of convenience, and as soon as we get V1 out the door one of my sub-sub-missions is to try each main tool against FPSC and ensure a good level of interchange exists between them, makes sense in the grand scheme of things. As a veteran of forum posting though, I must add that the definition of sub-sub-mission is that sub-missions come above them, and main missions come above sub-missions. And of course, urgent missions come above the regular missions. As a master of deligation these days (if not spelling), I will try to get the S-S-M task assigned to a willing third party as this information would be invaluable if you are considering saving cash by buying a bundle.
