Part of why some (me included) feel a static line is good. If you hit the tail after getting out, you may be unconscious (similar to your ship hitting the bottom of another, etc.).

Yes, you may get tangled in the line and it slows/prevents chute deployment.

I believe ours is usually 20' or so, enough to clear the tail. It is in a small coil (enough slack from cabin mount to rip cord of maybe 4') with a single wrap of electrical tape to maintain the coil until needed.
