I played briefly with an old-school drummer whose kit was bigger than the rest of the band put together, double kicks, two floor toms, five rack toms (seriously), more cymbals than an occult convention.
After our second (and final) gig together I took a close look at his kit before he broke it down. Four of the toms had heads that had never been hit, and most of the cymbals were as new.
Go figure.
Well at least he didn't have a 48" gong hanging behind him.

At a venue where I've gigged regularly for years there's another regular band who are good enough that I go and see them on my "evening off" if they're playing.
Their drummer has a similarly large & complex kit but he actually uses every bit of it, and in a tasteful sort of way.
I mention him because he always gets to the pub a full hour before the others, so that he can spend the extra time setting up his kit and then mic'ing it up as if he is playing Glastonbury ... kick drums, overheads, clip-ons for every tom, the whole works.
In fairness he sounds fantastic, but it's an awful lot of extra faffing for - I would have thought - a pretty limited benefit.
