Not so fast there,I've been working on this concept for a while now!
Frankensteined some old Infinity 422 heads,but it's a PITA to lighten the 9 thru (s) wedges.
Using some Kuro Kage shafts also instead of steel at 8i lengths.
Just found some old Maltby KE 4's on Ebay which should make the weighting much more
easier to accomplish,without having to sabotage the looks of the heads.

Having all the irons playing the same weight and length makes sense to me in the fact you only need
to play the ball in one position and use the same swing for all.
It's really not a new concept/theory,been around for a long time,Bryson just gave it new life!
