Yes, I've seen videos and know of drummers who had them tuned too low IMO. They can sound tubby at a tuning where another head may sound good. Keep going up past that tubbiness and then the head starts coming into its zone. They really do open up and have a nice tone and pop at higher tensions. I don't tune mine super high like you do, but it is slightly tighter than other tunings I use with different heads. I think the thickness of the head gives it that "thicker" sound and still retains that mid-rangey punch at a higher tension.I think the only way to utilise that head effectively in terms of tuning is it just needs an above normal tension......for me, exceedingly high. It just hits this point where it truly opens up and explodes.
