Here is a Millie DC. It has a lot of maple- the back, top and neck. Upper register access is easy. It balances well enough.
A consideration with a blue guitar is that it will very slowly have some yellowing emerge.
The original owner swapped out the HRWs with a set of PRS pups, which sound very good. I have the HRWs sitting in the case pocket, but so far have not had the urge to install them.
From an aesthetics point of view, a well done burst is grand. Black is elegant. I like block inlays.
I got a Les Paul Supreme earlier this year from a friend. There are similarities to the Millie series. The Supreme has solid woods with a lot of body hollowing, so both the Millie series and the Supreme are fairly light. The Supreme is less "neck heavy", but in neither is that a real concern. The Supreme has no back cavity cover. PIckup and harness work is doable but challenging.
The better return on your dollar investment is the Millie if you plan to keep it.
I'll add a little controversy. Of course every element in the signal chain and instrument affects the tone. I play the blue DC through four amps. Each takes the same instrument but sounds different. The Supreme is most like the chambered but has no back plate.
I wish I had kept my Millie Eagle 2000. I had a lot of time with that guitar. I don't even remember why I traded it now. Oh well.
