Great sounding heads. A few things I would note however, having used these heads live and in the studio: Great heads for the studio. Sound big and deep. They make the drums quieter than normal heads, which means if you have a standard Ambassador on the snare and these heads on the toms, you will hear a volume difference between the toms and snare (the toms being quieter than the snare). Which then leads you to this: You will hit the toms harder to get the volume you had to get before (will not matter if you're mic'ed up). If you hit them hard, and a certain velocity they will start to lose their nice tone and start to sound like "doink" (for lack of a better term).
