...different bows are made for different broadheads
Too bad bows don't come with a list of broadheads they're made to shoot.

IMO, it's more a problem with arrows than with the bow. You put a quality broadhead on a quality arrow, like an ACC, any bow can be tuned to shoot it perfectly. I've not seen an ICS-type carbon yet that can hold it's own against ACC's, or even XX75's for that matter, when it comes to shooting consistently well with a wide variety of broadheads.
