LF Yak and 3dBatix Extra - two great planes.
Though there is no doubt that LF Yak is a great plane, there is another one that might interest you. It's Extra 330 from 3dBatix. I have built both with similar configuration - 6 mm depron, 36 inch WS, Hacker 20-22L, 1045 prop. Both came out almost equal in weight. With my rudimentary 3D skills, I find it very difficult to conclude which one is better. I love both of them.

Edit: That Hacker is a clone from HK. But what a fantastic motor!
