First thought is this: if you've been playing thrash for an album or two, you're going to get bored and explore new horizons. No one except that pathological wants to keep re-making Dealing With It. Once is enough.
It's like those Discharge clone bands that all live in vans by the river. Keep hammering on that dead horse, boys, maybe it'll be 1982 again someday.
If you've mastered thrash, speed metal or death metal is the next step.
DRI fits into your pattern with Four of a Kind.
