I will give a review of the Lingyun 2 (not lubed, didn't change tensions) right now.
Speed: Fast. It took me a day to get used to it.
Overshooting: Once you get used to it, it really doesn't overshoot.
Cornercutting: very good. About 45 degrees, but you really don't need to use it once you get faster of course.
Reverse cornercutting: half a piece.
Pops: very resistant to pops. Really stable, it has torpedoes of course.
Feel: crispy.
Overall, it is a great cube out of the box. It's so awesome, I didn't need to lube it or tension it! Of course, you could lube and tension if you want to. Speedcubeshop has the cheapest Lingyun 2.
