Not Sal or Eric, but...
Spyderco was a very, very early adopter of CF. It's a material they know and love and a strong part of the brand identity.
Spyderco can and does get solid CF whenever they do sculpted scales in Taichung, and they use solid CF at the Golden plant and in Japan (IIRC, there are a few shops in Seki and they use different CF).
That said, they seem to have found a supply that can deliver good quality-for-price with the laminate used in slab-scale CF in Taichung. There is no denying that it's a compromise, though it might not be as simple a compromise as we expect.
Sal has said the cost differential is bigger than we tend to think.
Sal has also said that they like the look/feel of the laminate.
I suspect that there may not be the same pattern/texture/density available in both laminate and solid with a price differential being the only reason to pick one over the other, but of course Spyderco also needs to purchase volumes that make all of these things tricky.
As a hypothetical, suppose their supply for Taichung sculpted CF has A+ density but only B+ surface finish in the form they buy it in, compared to a 300% markup for A+ surface condition.
Now suppose the fancy weave is only available in laminate, and at the same price as B-grade solid CF.
There is no practical downside to the laminate (I mean, sure, it weighs a bit more, but not by an amount that means anything) and aesthetically it's a good pattern/texture (compared to other CF that's out there, even some of the older "solid" CF Spyderco has used).
If you value the "authenticity" of a solid slab of CF, it is a compromise you probably find disappointing. I've made the comparison to veneer on furniture vs solid hardwood; I don't buy solid hardwood furniture, but I understand why someone would think it's nicer.
If I had my way, we'd just use paper micarta and black or blue G-10 on everything... so I'm not the right guy to tell Spyderco what to do about CF. (I also don't like titanium slabs.
I like the look of side-grain "blackwood" CF, but I don't think there are many sources in the volume Spyderco needs and it's definitely not worth a big price premium for me.
