I run both combinations, depending on who I am playing and what we are doing. I am SOOOO looking forward to the 1.03 Full patch, so I don't have to agree on a version each time I play a game.
The Helo Dipping doctrine is for AI helos only, although I imagine that it would enable dipping behavior for the FFG helo when it is on Helo control, although I *swear* I've seen the helo dip when under human control, but that could be my imagination, as I don't play with the FFG as often as I probably should.
You can get the doctrine updates at the CADC under the 3.00b Mod thread in the mod forum, or at Bill's
www.subguru.com site as well!
