I disagree, but you know that. I feel the way you do about my Powertones. Have you tried one? the 3 ply Clevelands from 1964ish - 66 are the ones to go for.Coaxing different sounds out of the same drum is a function of how you play it. I can get a dozen different sounds out of my Black Beauty just by how I play it. And after how you play it, the head's always more important than the drum when it comes to what the thing sounds like.
However, the way a drum feels; the way it reacts to your sticks (assuming identical heads) is a function of the drum's design and construction, and this is where I think the Dyna-Sonic excels. It's just plain easier to play and it responds more quickly to small and large changes in sticking than any other drum I've ever played.
I can get my Dyna-Sonic to sound identical to my Black Beauty, and vise-versa (although the BB has one distinct overtone that the Dyna lacks). And if I fiddle with the adjustments (read: muck them up a bit) I can even get my Dyna to feel and play like my Black Beauty. But I can NOT get my Black Beauty to feel and play like my (properly-adjusted) Dyna-Sonic no matter what I do to the BB.
This means all the difference in my playing, but it may not make a bit of difference in yours. The only way to tell is to play one. The experience is not transferable.
I played a COB Dyna from 1967 - 1981 because I couldn't afford to buy a second snare, and I never really cared for it. I lump my 2 1980s XP10 Supertens, 1981 5" XP10 Dyna and 1964 5" fruitwood stain blue sparkle Dyna in the same boat: 10 lug snares that don't play any differently from the 6 and 8 lug snares, but sound choked and need too much attention to getting them to sound decent.
