There are good broadheads and bad ones out there. Many like mechanical's many like fixed. I shot mechanical's for a little while and was not impressed really at all. Some swear by them but I'm about as old school as one can get and just didn't see what all the fuss was about. Get a good cut on impact style broadhead such as the Montec or another excellent brand is the Slick Trick. I use those on my slower bows and my Traditional recurves. Both of those will fly right dead on with your field tips, or at least they do with all of my rigs. Never had to change a thing on my bow to switch from FT's to BH's while using either brand of them.
