I've spent the last few days messing around with bidou, and I must say I'm a huge fan thus far. Personally, I've always been the type that strives to find the best control scheme in a game, so this is right up my alley. The following setup has felt the most natural for me:
L - special
ZL - jump
R - attack
ZR - shield
In "bidou mode", I've gotten the most out of PP crouch / PP spot dodge / PP d-tilt mixup when spacing away. When spacing towards, I've noticed that PP -> turnaround attack is a lot easier to input than quickstep -> attack. As far as I can tell, the difference seems to be quite minimal.
Out of bidou mode, the right stick makes SH wave bounced dancing blades -> f-air (or u-air) incredibly easy. This move gives you nice backwards momentum if you delay ever so slightly. Also, switching between normal/down/up variations of dancing blades is pretty handy.
I'll keep messing around with bidou. Will keep you all posted if I find anything else.
Edit: the short hop u-air listed in the Reddit thread doesn't actually work as intended. It does give an immediate u-air, but it's a full hop instead. Less useful in my opinion
