Flight- Excellent, you find a better flying fixed blade head. Though I've have the main blade bend very slightly and it would throw it off significantly.
Penetration- Probably the best you'll find
Blood trails- Pretty decent, they don't create a huge hole...

I shot these fora while, but then found the Slick Tricks that: Fly just as well, Penetrate and shatter bone extremely well and create massive blood trails!!!!
