Here's my take on it:
While doing a cycle you have to determine which of 2 goals you'd like to achieve. Build mass or loose fat while retaining current mass. Trying to do both often leads to poor results.
So you need to decide which is more important to you: Building the muscle or looseing the fat. Personally, I believe that it's easier to loose fat than it is to gain muscle. So I'd worry about shedding the fat after the cycle is over.
However, a little cardio never hurt anyone
