The 6's and 8's have a more open grip than either of the McM's, if that's a consideration. I personally don't care for them.

My favorite Manners is the EH2, more closed grip, bigger palm swell, and higher cheek height, so no need for a cheek piece.

EH3's are similar, but with a thinner grip, and shorter cheek height.
