Yeah the heads are doing the biggest difference actually.

Ah proper bags is also a very important thing I realized. Especially if you go to gigs and it´s very warm. Last gig my new resonance head of the snare broke due to not having a bag, so now I bought bags for all. :D

That´s the good thing about drums, upgrade in stages.. Oh yes the cymbals I want cost around 1400 Euros. That is alot. But I will just buy one after the other.
