I only have a limited amount of input here, as I've only owned one Eames-shelled drum. That was a snare custom built for me on a VERY thick Eames shell with Rogers Dynasonic hardware. I wish I could remember the number of plies, but I cannot.
Sadly, I really did not like the drum, but it was my fault, I guess. I fell to the hype that a really thick shell would do this or that, without having heard one. And for me, the thick shell did not work - personal preference, I just did not care for the sound. This was WAY before the internet and YouTube, sound samples, etc, so I really had no way of comparing before I ordered, as I knew of no one with one of these drums to give a listen to. So, I got rid of it. And resale value was not good, compared to what I paid! LOL
But the shell did seem to be well built, I guess. I did not like the way the outer ply seam was finished, being used to a smooth butted-joint seam, but that was the only negative. The builder did the finish work in a nice walnut stain.
So that's all I can tell you. I know it's not really a comparison of YRC vs Eames, but it's all the experience I've got with Eames. Good luck with your decision.
