Which should you choose?
The Cable Fly keeps constant tension on the muscle through the whole range of motion. The Weighted Straight Bar Dip adds external load to a bodyweight pattern for direct overload. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the pectorals adapting.
