Honestly, I surprised the 51 is over 1.0
+1. Plenty of good 51 sticks, but far, far more n00bs.
Steve, 412th and OLDemon cant make up for em all.

The Yaks, I would say, I "fear" the most. Actually, I try to avoid them in furballs. It is a very capable fighter and the light ammo load almost ensures that a decent cartoon pilot is driving it since most newer players are horrible shots (present company excluded since Im still a horrible shot).
1v1, sure. But if we're all going to go around in a circle taking cheap shots in a horde, I'd rather the Yak not be saddled up on me the whole time.

Thinking about it, I'm more wary of Yak9U's than I am of Spit 16's. The 37mm Yak? Not so much. Performance falls off enough to allow room for exploitation.
