Hi Archie,easy way to find out call CS they will be able to help you

They are not currently on the shaft menu, but that doesn't mean they won't use them. Have your Titleist retailer call the custom club group and ask. They do occasionally have "off menu" shafts available. Expect to pay a premium if they will use them for you.

I have a question about the AMT blacks
I have a 80mph swing speed. I was fitted for the T200 with Reg flex shafts. I have the opportunity to get an incredible deal on a 4 thru GW with AMT black stiff shafts. Anybody have any feedback of how bad this may affect my game. I have a short back swing so not sure how I truly load the shafts
The AMT is flighted with changing weights as the clubs go up so wasnt sure if that was more forgiving between Reg and Stiff
