Carlini is better to the pins and to the right while Poulter is more physical (blocking/defense) and sets the middle better.
Well, Poulter is taller, but Carlini has better blocking and defense than Plouter, especially defense.
Hancock is the most eye-catching setter of them three, but Carlini and Poulter are definitely the ones that fit better in Karch's system... It's not that I agree with said system, but it is what it is
I agree with you. Hancock just doesn't fit in Karch's system. Fast and flat balls setting to position 4 is the weapon. But Hancock's setting to position 4 is really problematic.
