The reason to use an extra movement for the triceps, would be to train the full range of motion IMO.
So whatever excersise you pick, make sure you pick one that gives you a full range of motion, it's not as important to go as heavy on this excersise IMO.
You're going to go heavy on the bigger excersises such as benchpress, close grip benchpress, board benchpresses and dips.
On this excersise, I just focus on getting a full ROM.
Usually, I do frenchpresses with a rope from the low pulley, with a moderate weight.
