Just short of having a second bow to take, might conceder having a back up string that is already set up with peep, loop, string leechs, and of course a portable bow press. If the string is shot in, it is simple to replace a broken or cut string and cable. Also could take a new site, or a set of fiber pins to replace broken ones. Should at least have two releases with you, just in case. Having all of this for back up is cheaper than having another bow, and much easier to pack. And for anyone that carrys different arrow heads, judo, blunt, broad, you should always practice with each to know if they impact the same point. That should be a given!
