i usually make my club bangers double timed... 140-180 bpm... sounds fast, but when double times sounds the same as half the tempo... but i do the double timing to make the hi hat/tom/drum/snare rolls easier... and for the sounds... do whatever you want.. you can make a club banger with strings like scott storch... synths like lil jon... even piano, brass or w/e... biggest thing with club beats though are the way they bang, if they don't bang... it just ain't club... try using thumping basses, or 808s for that
