Here's what i got from Tony.
The lighter coloured shaft is old growth maple @ 12.8mm with Kamui Original M Tip
The darker coloured shaft is bowling alley wood @ 13.1mm with Kamui Black Soft Tip
They both play firm, however the bowling alley shaft is slightly stiffer but not dead. It also hits with a higher pitch ping despite having a softer tip on.
Interesting that the darker one has the "ping".
I'm not even sure what "old growth" means anymore. People seem to use the term differently. True old growth is beyond rare.
But anyway, my shaft resembles the bowling alley shaft you have.
It's thicker, so I would expect it to play stiffer...but that "ping" quality is interesting. Personally I like that as long as it isn't too sharp. To me it was always a good sign.
