Yeah Taz- except most mech's have blades that need to swing open from front to back before they get to that good angle. On a perpendicular shot the design functions flawlessly. But on a sharp angle shot, , they are being forced into flesh on the short side (at 200+ fps) as they open, and keep in mind that the leading edges of these blades are dull (the part that grabs and opens the head)... I think they start to plane as that short-side blade swings open.

Again, this is why I like the rearward opening blades of the Snyper. The tip bites first, then the blades just slide out backwards without having to pivot around 180 degrees.
