Drumheads, drumheads, roly-poly drumheads!

So I wanted to replace my cheap original drumheads that came with my new drum kit. They are thin and ring a lot more than I would like. Another detractor is that they are clear (YUCK!!!).

So on the advice of Jesse the drum guy at trade-up I picke up some Evans Genera G2 Coated batter heads for my toms:
A two-ply head (7mil each) featuring extraordinary consistency and durability, the G2 offers the perfect blend of depth, sustain, and attack. It makes small toms sing and floor toms growl. The coating adds additional warmth, focus, and depth.

and a fancy Evans EMAD head for my Bass:
Tailor degrees of damping and attack without removing the head or reaching inside the drum. The EMAD is a 10mil single-ply with two interchangeable damping rings that maximize attack and low-end.

Now I am really faced with tinkering with the sound because my kit sounds alot different, particularly louder that before. The tuning isn't really a problem except the back heads still seem a bit screwed up. I figure trial and error will do it.
