1 - no drums are classified for any specific genre so calling them hardcore drums is a complete crap statement
2 - theyre not at all the cheapest customs...in fact, theyre one of the most expensive. eiparch, phattie, and even spaun are all cheaper than truth.
3 - truth drums are not what theyre cracked up to be...as its said in another thread about them, theyre just overpriced keller shells. if you want truly custom drums get masterworks...you pick everything about them, and you wont spend too much more.
I've seen two drummer in two different settings use Truth drums. One was at a small venue and the band was of the punky/rock persuasion and the drums sounded HUGE. The other was at a fairly large venue with Good Charlotte (my girlfriend made me go...please don't make fun...lol.) and the drum sound was pretty bad. I'm not sure if this helps at all, but that's been my only experience with them.
