If you were fitted by an authorized Titleist fitter, they would not have had any shaft with a Titleist adapter that was not going to be available. As for the up-charge, any Titleist retailer or pro shop can call and find out how much, if any, upcharge would apply. Give them a call. This is more of a users site so you won't really get customer service answers here. Sorry, but pretty easy question to answer by a product supplier. Best of luck and hope you end up with the club that works best for you.

GolfUSA of Manhattan lists it with a $30 up charge. They are an authorized Titleist retailer so the plus up should be the same or at least close.

PS...the Custom Options booklet list all available shafts and notes if there is an uncharge or not, but is doesn't list the cost of the uncharge.

Not sure where you were looking, but it's under clubs. Then go over to custom shaft options and click it. Anyway, Hzrdus Smoke Blue RDX 60 and 70 in 6.0 are listed and carry an upcharge. Hope this helps.

Found a hazardous black 6.0 and there is no upcharge.

Chuck, Dennis was fitted for the Hzrdus Blue RDX shaft, not Black. You should refer to the Custom Options Booklet, not the Shaft Performance Guide because it's not updated with all current shaft offerings (it lists shafts no longer offered and doesn't list all currently offered shafts).
