Float/Capacitance sender, Flop/Normal pickup?

I?ve been torn between using gas tank ?Flop Tubes? VS ?Normal Pickup? and gas tank ?Float Senders? VS ?Capacitance Senders?. I?ve decided to do both. The left tank will have a Flop tube with Capacitance Sender and the right tank will have normal pickup with a Float Sender.

I like the idea of having both so that I can have experience with the way they both install and they way they both perform.

Any comments on doing it this way?
Can anyone see a problem with this kind of setup?

Use Fuel Flow Transducer

Use the cheapest and lightest standard fuel float system. They don't work anyway, and can't be trusted. But install a fuel flow transducer by either JPI. Then you'll know your fuel burn, amount on board, time to exhaustion, etc. And it will interface to your Garmin 430 when you install it.

Measuring Fuel Level

Hasn't anyone considered the Princeton capacitance fuel probe system from Aircraft Spruce in an RV?? It sure looks like a slick system to me!
