Personally, i'd be dropping the extra $400 for the Pro series. I believe (at least during their original conception) they were based off the Blue series but have evolved with apparent new valving tech etc etc.
The BC's were super harsh ride wise, felt like the road was covered in potholes almost (this with damping at softest), but they did feel a bit more pointy initially through corners, i felt like there was considerably more understeer at turn in on tighter radius corners (but this is not really a like or like, considering the difference in wheel size, tyre choice, track temp etc etc)
