Both super heavy bb shell options in steel context. 30mm axle is doable now with 68mm threaded and BB86 so no real reason to add weight with pf30/t47

But more aero?

Yep indeed, wondering why op is considering PF30 in the first place really so throwing that out as an alternative.

Pmw t47 shells are negligably heavier than their BSA counterparts, much thinner wall thicknesses than the originals.
I'm a fan for a few reasons:
- Di2 and dynamo routing much much easier.
- I can use hologram cranks.
- Much easier welding profiles, less compound mitres.
On the down side you only have Chris king and white industries supplying bb's in any number, although white industries have said they will make them until they close.
- Di2 and dynamo routing much much easier.

Considered the T47 standard too as you get to choose?
