Iron and Driver Shafts

Hi, couple questions for you, I am in the market for some new titleist irons, current gamers are 695mb's project x 6.0 flighted. How similar are the new pxi shafts compared to px flighted? would a 6.0 in pxi be similar to 6.0 in flighted? or move to 6.5 as I am on the edge already. As for heads how do the cb's compare to the 695mb's? and for the driver shfaft question, I was wondering if you guys offer the matrix white tie yet? current gamer is a fubuki 63x in my 910d2 just looking for something different but similar attributes for the 913. Thanks
