I always had jusr two ctmbals and hats for years,but in the mid 70's expanded piece by piece to 5.I used 3 chashes,one 12" slpash and a ride and hats 2 up 2 down.
When I started playing again,it was a ride 3 chashes 1 china 2up 1 down,wich became 2 Down.Then 3 up two down 3 crashes,1 splash 1 ride and hats.
Now it's mostly 1 or 2 up ,1 or 2 down,2 chashes,1 splash,a ride and a china.Usually 1 up,1 down 2 chashes and a crash ride with my 60's Luddies or 70's Superstars
I might start scaling back even more,as I'm a big fan of a Band called "The Reefermen".Their drummer uses a vintage Ludwig 4 piece and 1 crash ride and a chash,both on the same side.They do mostly covers,and the Best Zepplin medley I've ever heard(mostly instrumental),and their lead guitarist is excellent.What this guy can do with just a Strat and tiny amp is amazing.
But I digress.Cocktail kits were all the rage in the 50's,and seem to be making a comeback,and most are just 1 crash/ride and hats,1 small snare and a floor tom/bass drum combo,with the pedal under the floor tom.
And then,there's Terry Bozzio and Mike Mangini who need a truck to move their kit.
I say play what makes you happy..Large or small ,whatever you play has to make you happy,or it's just a job.
