I did the same thing for my new SM-10 Raw 54 coming soon to me. Did a bunch of research and then a buddy of mine got fitted for some "other" branded wedge but got his sand and lob wedge in the Project X Wedge shafts and he loves them. I'm gaming the Project X LZ stiffs in my T150/T200 combo irons I just purchased and so looking forward to seeing how that new 54 plays.

Looking forward to others experiences too.

I have the Project X wedge shaft in my SW and LW. My SW is 54D grind and my LW is 58K grind. Love the feel more than the shaft that comes with it.

I use the Project X LZ for my wedges...such a great shaft!

Well the wedges came. After 6 rounds now, I'm happy to say I really like the Project X wedge shafts. I went with the 6.5's to match my set of T100's. What I've noticed is that they has a little more flex. You can really feel where the head is, especially on the partial shots, etc. They just feel a bit "softer" to allow you to hit the different shots.

The project X wedge shaft seems to better paired with std project X shafts .... assuming you play these. That is the feedback I am hearing from players using shaft...

IMHO
