Hi, the Wilson ratings seem odd. Can the midsize F5 irons really be more difficult to hit consistently from the sweet spot than V4, V6 and Staff Model? At 200 the F5 rating seems very low.

Answered question

Relatively low c-dimension with a higher Vcog are putting the hurt on the Wilson’s MPF.
Compare to the deep red II from 2005, and it might make more sense.
