I love them. Been using them for two years and could not be happier. They will fly just like your field points. Actually the entrance hole sometimes is larger than the exit hole. If you go to this post http://forum.hunting.net/asppg/tm.asp?m=822495 you will see the results I had using them this year. One real advantage is quartering shots, the design will not deflect like some other mechanical heads. IMO one great broadhead.
