I use them for just this year. The choice of these skins were justified by the use of its skin by my "mentor" George Kollias. Results: simply monstrous! A clicking sound with tight chest, or a thud and deep with a voltage more "loose". The sound is warm and perfectly controlled, perfectly clear sound even during passages most "nags" of my death and Black groups. FYI I'm using 126.96.36.199.14 and 16, only the 8 is a little hard to set 14 and 16 are simply monstrous! Good price / quality ratio, choice I will ever eyes closed.
I play on a Tama Superstar. I wanted to change the skins home and asked my teacher (a career in jazz), what I had to be skins. He advised me G2 coated on toms, which had its drumkit.
It was a very good advice, despite the difficult adjustment for my taste, the sound is very good dry, somewhat serious. On my 10''tom, I have very tight and when I type the sound of the snare reason (but it's not a good patch).
So, I recommend it to everyone, but we can still do better!
