Mechanical broadhead from a crossbow?

Does anyone use them? Can I shoot a rage form it or is it too fast? Problems with opening in flight?

Rage makes a BH especially for crossbows. They have a 1 3/4 inch cut. Regular rage will open upon firing in a crossbow.

Quackaholic1 is not kidding about the standard rage opening up with a crossbow, they sure do make some noise in flight when open early.
