Bolduc hybrid pinblock

[David Love]

I spoke with Bolduc at the Calif State Convention and I think the reason
behind it was cost.  The new block comes in about 30% cheaper.

Assuming a 1.5" block, close to 25 layers of the thin stuff 
would fit in there if it were all thin stuff, which is nearly 
Delignit density, except it looks like maple. I expect they're 
making it. And yea, I don't see the point of the layering 
configuration either.

I've settled on about 9mm of Delignit (somewhere between the 
capping thicknesses shown in the photos) on multilam maple 
blocks, as an optimal balance between performance and cost.

Me too. The real one, that is.
