why not both? :)

variety is the spice of life, so they say.

i love long, smooth mixes, but i get bored easily, so some variations help. a bit of cutting, some double up tricks, some fx fun...it all has it's place.

what i absolutely abhor is sloppy tricks tho. if yer gonna do doubles, get it on beat. if yer gonna cut it up, at least make sure the record you're cutting with flows...or it sounds crap.
if you want to use fx, use them sparingly or subtly.

just my three cents...
