The whip and synthetic backstay is the choice of most. Of course with 20 degree swept spreaders you can sail most of the time just fine. But when you are running deep and you stuff a wave and the hull wants to stop and the rig
doesn't or you jibe with a liitle too much gusto you stand a good chance of the rig
going over the front. Raking the rig
aft will better your clearance, other issues aside. You can also cut some of the roach off and clear just fine. The backstay is there to both flatten the main and to tension the headstay which will flatten the jib
entry as well as make it furl better. If you don't care about these performance issues then cutting the roach should not be an issue.
