I believe the FH020AA is the best available.
Here's mine on my 695:
After a few weeks use, I can report that it doesn't get hot at all, and that it holds a more constant 14.4V than my old OEM regulator, which used to overcharge my battery a little at high revs.
The only downside is that it isn't a straightforward swap, as its sized a little differently to the stock one. You probably don't need to go quite as overboard as I did fabbing a mount though.
Oh, and buy the proper crimper for the furukawa terminals that it uses.
It's got plenty of excess capacity. It should be fine on a single phase alternator.
