I can appreciate that learning SIMPL is something that I should do in the future. Unless I'm misremembering, changing to Studio means that I have to change to a 3-series processor and can't use my BiPads anymore. I have a ton of custom programming, so either case will mean weeks worth of work. Shouldn't changing the built-in module to be SB compatible take less than an hour (hopefully much less)? I remember changing a serial module was pretty quick.
