I'd start out with m-drol myself, 20, 20, 20, bridged to h-drol. I personally didn't notice anything from h-drol.
M-drol gives really good gains, so doing the milder h-drol after will help you keep them. 3 weeks alone isn't much time for your body to adapt.
I always run nolva 20,20,10,10, even after a m-drol to pplex to h-drol bridge I did.
