Having followed CT's HP Mass principles and now I'm trying his SH Complex; I'd say do his program as written first and use the off-days for assistance work (Rhomboids, Rear Delts, Trap's) Lat's / Bi's, and / or Neural Charge workouts. There is so much pressing involved in his workouts that I personally don't find much need for direct tricep work. At most I've considered doing Dips on an off day but purely bodyweight. Figure it this way, if you do all 6 sets of each exercise at the high-end of his rep range you're getting a ton of tricep work in. For example:
BP from Pins 6 sets x 3-5 reps = 18 to 30 total reps
BP: 6 sets x 3-5 reps = 18 to 30 total reps
Speed BP: 6 sets x 5 reps = 30 total reps
Plyo Pushup: 6 sets x 8-10 reps = 48 to 60 reps
Medicine Ball throws: 6 sets x 8-10 reps = 48 to 60 reps
On the low-end of the rep range you're doing 162 reps, high-end 210 reps and that's just chest / deadlift day, that doesn't include shoulder day's pressing. This is only my first week of SH Complex and I may feel differently after week 6, but I'd try the principles as outlined first. I would suggest trying it as is and then adjust for your personal needs.
