Hi,
I have Rifle Flighted 5.5's in my recently acquired R7TP irons. This shaft was the recommendation after a session with the guys at Precision Golf and thus far I am very happy with them.
They feel very stable and well suited to the R7's as my previous MX23's with TT S300's never did-the heads didn't feel "connected" and they flew far too high. Well worth trying out and see if they suit your game after you have been fitted properly.
By the way Royal Precision are now owned by True Temper as well...
