I'm also bulking, and while I know some fat gain is inevitable (that's just that name of the game), I've still stayed fairly lean by doing cardio on my off days only (basically these days I work on MMA technique).
I plan on hitting the track workouts HARD when it's time to cut, and when I have a enough muscle so that losing some while cutting, won't be the end of the world.
EDIT - I just remember though, everyone responds to stimulus differently. I know some people who get JACKED just running sprints and doing body weight exercises. I agree this is not the case for the majority of individuals, my point is only that you should try it all out, and see what works best for you.
It took me a LONG time to figure out how to keep BF acceptable, gain muscle on a caloric surplus and not overdo my cardio.
