To be honest the only difference, for the most part, I have seen between regular broadheads and xbow broad heads is the advertising of a thicker feral and maybe maybe some beefing up of the internals of a mechanical. People been shooting the same ole broad heads out of each for a very long time without having to have a separation of the two. But in this day and age most want to see "specifically designed for" on the package. The only way I can see that there might actually be a head just for crossbows is with expendables on the newer models that are reaching speeds up to 380 - 400fps. In my opinion a 100gr, 3 blade, fixed blade, with a 1 1\4" cut is just that.
