I agree with Terraj on the pause at the bottom, but feel differently about the calves workout. I would mix up long duration days with strength days. On the long duration days I would do lots of different excersizes and lots of reps to fully fatique the calves and convince your body that they are not large enough to carry the load. Along with your other leg work do both standing and seated raises with lots of work near the bottom to develop the lower portion of the calves and stretch the fascia. Then I would do my heavy workouts on other days, its my feeling by alternating major rep days with heavy days that the rep days will keep the muscle group fatigued as hell and the heavy days will cause new growth.

PS great physique good luck on the contest prep you surely got the tools for the job!
