Yes, they are as a special order, with no upcharge.

Yes, you may not find them stocked in stores that way but there are several options for shafts. I got the Tensei Pro Red Graphite in regular flex special ordered in my 718 T-MB's.

You can order them with any of the iron shafts listed in the custom options booklet...check out the link below.

The fitting cart will have the 7 iron and essentially all the shafts in the matrix can be fitted. Certainly every stock shaft for the AP1, AP2, AP3, CB, TMB, and MB will be available for the AP3 fitting 7 iron. Moving from the AP1 with the KK 65 g, we went through fittings from the 65 KK A-flex to the AMT-Red R-300 on the AP3. I'm very happy with the AMT-Red R300. ...None of the demo sets are LH, so I don't have to worry about what shafts they use. ;-)

Yes, they are. Titleist has a number of regular flex graphite shafts available in that range.

Did you go to a Titleist demo day or see a Titleist certified fitter? They should have most available shafts.

Yep I was surprised at the options available during a Titleist Thursday. I am now playing AP3 with Nippon NS pro 880 amc reg flex and I love them

I just bought a set of AP3, graphite regular shaft. My PGA professional at the course fitted me to these shafts and ordered them from Titleist. Great Clubs
