Cathi,

Any updates on these shafts?  I am about to place an order. 

Thanks

They are available to order now and will ship April 1st 

If I play a 5.0 in the regular Project X, would I most likely get the same ball flight in the 5.0 Project Xi?

Thanks in advance.

If I play the Px 5.0 will the Pxi 5.0 give me the same ball flight, or should I go with the Pxi 5.5?

Thanks in advance

Is there an upcharge for this?

There is an upcharge for PXi shafts. As we do not have an MSRP for upcharge shafts, please check with your local pro shop as well as your local retail outlet for comparison pricing.
