Callaway Razr X Muscleback tip size?

I know the 2007 version Callaway irons were all .355 taper then for 2009 they went .370 parallel in the X Forged. Does anyone know what the tip diameter is on the 2011 Razr X Musclebacks and the Razr X Forged irons?

Anyone?

The Cally Proto MB is 0.355" but would they change the RAZR X MB?
