A PB 10" would be cool.
Actually, and this is only my opinion... but, I think the PB10 is the odd one in the line up. It uses the same sphere as the PB8 so you have more thermal mass with a 10" mirror to try and cool in a sphere where air flow is now at a premium - bigger mirror takes up more space so air flow is affected. And, the scope uses the same diameter truss poles as the PB8 but they are something like 6" longer. This might add up to a slightly shakier viewing experience. To me, the the PB10 has always been a compromise - not the Goldilocks aperture - between the 8 and the 12.5.
