RE: 88" EF yak or 86" QQ yak?
If you truly want a "big" Yak then the EF is the one. I also just ordered one. The quality is unreal. These things are designed so well. I like the covering scheme way better than the QQ. For some reason his colors just look bland to me.
I could see why the QQ would be better IMAC. The EF is a fat fuse and big cowling. It might drag a little more than the smaller QQ. Being a 3D nut the EF is a no brainer.
So it's the same old story: Better depends on what's best for you. EF is better for me, the QQ is better for others.
