Hi Mark,
one thing I have noticed with the PA3X, is that they have left out a number of the European styles, like the Schlagers, they've left out some of the Latin ( or should it be Ballroom ) ie Chacha styles that were on the PA800. In short, some of the type styles you're reffering to.
Whether or not they'd suit you any better than the one's on the PA3X , I don't know, but there are more that could be added to PA3X from PA800.

I've finally got all the missing PA800 styles together that don't exist on PA3X. (Hopefully got rid of duplicates). Bit of a chore working out what was new & what just had the same name.

So any PA3X owners who want them, let me know.

I'm sorting thru PA500 currently. Even worse, some of them are in German . haahaa.
