Why are you keeping the P2?
Clinchers for me, a Veloflex Record has as low Crr as any non-track tub and a Conti Supersonic probably makes up for any increase in Crr in aeros.

I thought the GP4000S2 was the aero tyre
A variety of reasons really, but my excuse is that I'm going to set the P5 up as a 1x10 Di2, and use the P2 on the more sporting courses. Although in East Anglia, it's all fairly non-sporting, so it's a pretty poor excuse.
