Proviron is actually a DHT. People use it as an AI, but ive heard some cases of people still getting gyno when using it to control estrogen. 
In my mind, you only need 3 AI's for 3 different reasons.
1) Adex- For controlling estrogen. (On Cycle)
2) Aromasin- For lowering aromatization and preventing further creation of estrogen. (For PCT)
3) Letro- For running gyno reversals, or in cases of EXTREME gyno sensitivity, estrogen control(<-of death in this case).
