I had both. one of Kevin solid and one of his LD shafts.
I had no idea that he was sending me a LD shaft..
Hands down I like the solid maple shaft tons better.
Some of these LD shafts sound and hit different, almost like they are cracked or broke.
Its the sound and the hit that I don't care for.
He described it to me as a ld shaft of his design, better than any commercial shaft I've played with. Short ferrule with a stiff taper, 13mm.
