The move I think the OP is talking about would be almost better describe as a flat turn into an immelmen which is probably the best thing you can do against a con with more E. You talk about doing a split S which makes me think your not quite their in your ACM(no offense) but I see a split S as being a last option when you dont have the E or time to preform this move. A split S really just buys you time to get more E to use in finding a way to making the fight a co E fight where its who can win a scissors fight which is normally rolling scissors where most "even" pilots get to
The OP states one of the problems being lack of E when he finishes the maneuver, if hes in a fight, and his problem is not having enough E, then he needs to build up some E, there for split S isn't an entirely inappropriate move.
And no offense taken Junky, I have no false illusions that I'm some sort of uber pilot. If there is a gap in my education, I'm willing to learn.
