I used it recently for 6 months. Very good sound, what I wanted: serious, warm and round, with what it takes rsonance. Give a bit hard, because it is coated and a remo. But very good sound. I use it on a bass drum closed.

Unfortunately, as I said, it lasted only six months. Not very strong, then, when having to change his bass drum every six months, may return CHRE! knowing that score 45!
So:

The +: sound, serious, round, warm and alive.
the -: a solid 6 months or less (less if you play doubles with bat or plastic timber!)

So now I have to change it, because I am not (yet) Crsus, I'll find my way to a firmer skin! Its leaves have a slightly less good.
