Looking for some opinions/advice here guys.
I recently tried the new XRs by Callaway with the recoil shaft(f4)ithink they were 460 but can't say for sure, and really liked the feel and distance.
Here lies my dilemma. I don't want to pay the kind of money GT wants for the set, so i thought that if i get a set of these shafts and put them in my current irons (TM Rocketbladez with 85g steel)it should give me about the same result.

Here is where i need the expertise of the guys on this forum, suggestions,alternatives,heckling, all gratefully accepted.
I don't have club assembly expertise or equipment so all suggestions for alternatives to GT or Golfworks as an assembler would be welcomed as well.

Thanks
Boomer
