Well, for me the hybrid stuck out as the sound I was looking for. I've used many different heads with many different muffling techniques, so when I heard the hybrid with no muffling, I really liked it. Now that I've played it for a while, I've found that it has (compared to other heads I've used) some unique qualities. I can get more ring/resonance at the half radius point, then strike in the middle and it has almost zero ring. Probably all heads are like this to some degree, but even on my center dot heads I never noticed. I will try to record something the justify what I'm saying here when I get a chance. The head tunes up nicely and I am absolutely loving the sound. It is definitely my favorite so far. (EC Reverse Dot, Genera, Power Center Reverse Dot, G2 coated... and a bunch I don't remember)Great link. The Hybrid isn't bad, but that's really expensive.
I liked the HD, the HD dry, and the Onyx better on that video.
It seems like you can always tone something down with tape or moongel, or pedifix gel moleskin which is what I used on my son's set. I don't know if you can make a head less dead/damped. Maybe, if it has a ring you can cut out.
