OK, I'm going to contradict myself: I may be wrong about this, but I think the Paul chainrings are a proprietary pattern. So you've buying a phil bottom bracket, which is a lifetime investment, to work with a crankset you're probably not going to be able to get chainrings for in 5 years (or you'll be able to but it'll be a PITA). I would just get the $35 campy ACH bottom bracket. There are other campy taper cranks out there, but they're all $$$. If I'm going to invest in a phil BB, I want it to work with everything out there so I can still be running it in 30 years when I'm an old fart on a recumbent.

OK, I'm done
