Hey Ken,
that does sound very good. are you happy with the sound? Drum sound is very subjective. I tend to go for a lot more open/natural sound as opposed to the tighter, muffled sounds -- I think yours is sounding very close to the Roland samples you have probably been using for awhile.
and if that's the sound that you are going for then I'd say you succeeded. but you sure can't beat real cymbals can you?
I am curious about those EC1/EC2 heads. I went to the NAMM show when it was here in Austin last year and those really sounded good on their demo drums. I'm probably going to try them soon. Right now I have G2 clear on top and Attack clear on bottom. it's OK but not perfect. My drums originally had ambassador clear on top and bottom and I liked that sound but I've been experimenting with heads and 6+ years later still haven't found the perfect combo.
Now, on my road kit (a very early Pearl SRX which I confirmed is really a re-badged MRX--6ply maple--kit) loves the coated Attack single ply heads on top and bottom. I couldn't be happier there.
as for tuning, you might try making the top head a bit tighter than the bottom and see how that sounds for you also. and also really crank the bottom snare head-I mean tight. surprisingly it takes bit to choke the bottom head and can really make the snare responsive.
