Acoustic pickups for floating bridge

I'm having a custom built that will have a floating bridge (on a flat top) and am looking at pickup options.

From what I can tell from recordings and reviews the Fishman Archtop Guitar Pickup and K&K Pure Floating Bridge and Definity options don't sound that great.

It seems like Pickup the World has an option although I could not find a single recording of it and only one review (which was positive). Does anyone have any experience with this pickup or any other suggestions for other options?

Another option is a typical soundboard transducer setup like the Aloha Twin but I've heard that finding the right placement for that pickup's transducers is not so easy for a floating bridge setup.

Have Andrew ask the guys at Ko'olau. They have built a couple carved arch top ukes. Andrew might have a good idea as well.
