In short

Light, low-stack and fast with good ground feel; little stability, and a few find it dead.

Firm, stable and light for speed sessions; reviews are lukewarm, with several calling it flat or dull.

Light, fast and firm with good ground feel, but unforgiving for some on slow, very long runs.
