He says that good ballstrikers can benefit from blades, not just great ballstrikers. If you rarely work the ball, however, he doubts you would get much benefit from blades.
I suspect that because blades have smaller heads than SGI cavities, you could get better feel on impact with blades - less metal to absorb the vibration. I have split the distance and play GI Callaway X20 Tours, I can tell on impact what quality of shot I have with the X20 Tours; with the SGI, larger-headed X20s, I could only tell if it was a bad shot.
Also, some of you might hunt around in the Tom Wishon video clips. One segment shows a physically fit senior player who gets better launch monitor data with blade heads + lightweight steel shaft than with GI or cavity heads.
