Sawdust spawn for shiitake blocks

Stamets recommends creating sawdust spawn from just sawdust and water inoculated with 10% grain spawn. The theory is that the mycelium adapts its enzymes for the type of wood used in the substrate blocks and thus has a better start at growing than grain spawn.
Does anyone have experience with how this kind of spawn compares with grain spawn in terms of colonization speed?

I know this won't help much, but i put beech mushroom on grain, and it was really slow. I then spawned to sawdust after a week it took off.
Im thinking sawdust to sawdust would definitaly give an advantage, prob shave a few days to a week off your colinization time as it won't have to adapt as you said above.
but someone more experience im sure would be appresiated

I tried that method several times and it was slower than grain spawn every time. RR

If you use grain spawn to inoculate sawdust, use a liquid culture with sawdust added, it will have the lignase partially developed.

Per stamets books, I've also tried adding small amounts of sawdust to my agar and grains, but have never noticed one whit of difference in colonization speed later on. In fact, adding sawdust to agar seems to slow down colonization. In my experience, using one full quart of rye spawn per five pound substrate block gives excellent performance and fast colonization. The rye is an important part of the final fruiting block. RR

I've tried once with nameko with no results, however RR are you saying to add the sawdust on the agar or adding sawdust into the media?
I've found adding sawdust directly into the media slow colonization, instead adding on the partially colonized agar it raise a bit the future transfer.
However i've never tried the Stamets recipe but have you checked also the speeds in the next transfers? I believe is normal that the mycelium takes more time to digest the wood than the sawdust, perhaps this delay, at the starting point, will transform in a faster colonization in the next trasfer to the sawdust supplemented or not substrate.
Just my opinion

That's the theory, but I haven't noticed it in the real world. RR

One of the main reasons you would use sawdust spawn to inoculate Shitake blocks is that sawdust costs practically nothing compared to grain. You start with grain as it is quicker to colonize from agar, for some reason I have not figured out why. From grain you go to sawdust as it is simply cheaper and costs less to do large amounts, then with that you go to supplemented sawdust for production blocks.
Its a monetary thing plain and simple.
