Got to disagree with you on this one, I used to have a blue (NOT PL blue) in an R7 driver and couldn't keep it down. I went for a TM fitting and the fitter checked my R7 on the monitor, spin rates were between 5000 and 7000 rpm depending on strike. Certainly not a low spin shaft. A Proforce 75g shaft brought the spin down to sub 3000 rpm.
There is no way a proper Graffalloy Blue would spin this much unless you were slicing it like crazy. Think you may be getting mixed up with something else. May have been a made for TM shaft that was a shadow of the real thing.
To the OP, if you like the shaft you have now then try a slightly heavier version of it, around 70-75g perhaps.
