Hello, I placed an order 6 weeks ago for a 716 cb/mb combo set (4-pw) with project X LZ 6.5 steel shafts. I understand these shafts have been on back order but I have had two sets of these irons fail quality control. I am hoping someone from Titleist could let me know when they expect the next shipment of these shafts in and if they are aware of any widespread issues with these shafts. I'm wondering if I should switch to the KBS C-taper lite x as I know those are in stock and have already passed quality control.

Thanks
