Im gona have to agree. The same thing happened to me with a few remo heads, so i bought some other ones. Now my set is made up of all kinds of different heads. a few tom heads my 12" and 13" toms have the same heads but the rest are different. kinda gives it a different sound so its really varied in how i can tune the whole kit to sound.
Don't judge the whole company because of one kind of head you used...
It's like if I bought some clear Remo Diplomats for my drums and I was beating them like a gorilla and they just happen to break, I'm not gonna say all Remos suck because of one head I tried broke.
