Hi Frank -

Please excuse the delayed response.  There have been some recent changes with aftermarkets shafts and associated pricing structure. 

The Diamana Kaili 60 (shaft only) should have an MSRP of $350.

I can speak for the RIP shaft in saying that it is a lower torque shaft than the Titleist Voodoo and feels a little stiffer. To me the Titleist Voodoo was a little "whippy". Not to say the Titleist Voodoo was a bad shaft, but I think the RIP is better…

Why would you want to do that and what flex are you looking for?
