the pro version has a screen and holds all the algorithms - so much easier to deal with, without a cheat sheet
if you buy a pro and an xl for example & plan a bit ie set the order of the 1st 32 algorithms to be the same as the other fx aid then you can use the pro as the cheat sheet for the other module

I've seen you speak about this before, Jim. I know how much you love the pro. It is definitely a solution.
