Arimidex, Nolvadex and Proviron

Is this overkill during the cycle? Is the arimidex good enough to deter gyno??? I am just in beggining stages of planing but this is what I am planning.

Stats
6'5 260lbs 15-18% bodyfat

Going to get down to 225 and 10-12% before I even start

2nd cycle

1-12 200mg/week Test E
2-12 200mg/week Masteron
1-6 50mg/day T-Bol
3-14 250iu of HCG 2x a week

Goals: Quality Muscle only. I dont have a hard time with gaining weight so I am only concerned with quality muscle, vascularit and hardness.

Also I asked this in another thread and really didnt get a good answer. I currently do vigorous cardio vascular (ie. Sprints, Hills, Gassers, Bleachers). I want to make sure I am not risking a heart attack or stroke. My blood pressure and cardiovascular is excellent right now so i am not sure I need to worry about this but just covering all bases.

PCT Nolvadex/clomid

I have seen so many conflicting threads on PCT that I dont know what to take. I would rather stay away from Clomid but it seems to be the most common along with nolvadex for PCT.
