Indeed, most cables are shielded these days so there is no worry. Twisting them won't help if they are well shielded to begin with. Check to see with your cable manufacturer if you aren't sure about their shield quality.
Now if they aren't shielded, a rat's nest is the best solution, believe it or not. You certainly don't want to coil the slack up, nor twist tie them together in parallel.
