Agree on the shoulders and I would of done similar, but if pickup was a concern then I would understand the thicker shoulders. To be fair Streaky could of done this at the CAD stage, if the client wanted it
Then that would be a bespoke not a custom.
Customs are cheaper than bespoke as it entails less time in the design stage. You get a chose of a few set spines, edges, and concaving. And then add your weight, the density of cleft And it's is calculated to size. And then cut.
Bespoke, is designed form the off on cad, to your spec.
And this why I have paid the extra for bespoke on my bats as I get to see a 3d cad drawing off said bat, and say "hmmm take some wood from here, move to there, make this bigger, that smaller. Etc until I'm happy with the design.
