Sirloin, I accept your claim as you've experienced it. My own experiences say a slow turning G10 cannot turn as well as a pony. There is a marked difference.
But the way, if I am fighting a slow turning G10, and I "go more flaps", then the g10 goes vertical, I'll retract my flaps to one notch and hose it out of the sky.

That move simply does not work for those who are ready for it.
Even in slow yoyo's, I have no trouble getting my nose on the g10 for a gun solution.
IMO unless the g10 goes vertical before the fight gets slow, it is dead meat.....every time.
in the last example, the pony is in big trouble....better nose down and get the G10 to pursue so that it is fast enough to lose some elevator authority. I recognize this problem early and stay off grabbing g10's...there's a guy who is really putting the fight on his most favorable terms.
