I chose the same options. John makes phenomenal instruments, with the best customer service you can find anywhere.I have a Duluth Shell about to be finished.
You can get it in any thickness, I chose 5mm, but also you can get the Concave re-rings as well for no extra cost.
The Recent DW TrueCast is for sure from Duluth, because the Hoops are Aluminum Bronze just like Duluth offers. I chose the Tree Bronze Shell and the Aluminum Bronze Hoops.
Thats what's foul about DW though. They charged an insane price for a shell and hoops they paid a little over 600 bucks for AND that's if they paid retail. The Brass Hardware isn't that expensive because I had custom Brass Tube lugs built for me for 100 bucks shipped. I mean, I had an opportunity to spend 500 bucks on Solid Bronze Lugs and they still wouldn't justify DW's cost.
I feel like any one who purchased the DW True Cast drum should feel duped. DW just cashed in with very little work.
Funny thing about DW, and to your point, is that they're charging $1,600 for this 11-ply maple snare:
