The only potential issue with V-Belt is that when you put a shock through the system the V can dig into the pulley and actually transmit a lot of force - if you can found a round belt it will be a lot safer, though as people above have said - many are using V-belts without any issue.

We never had a problem with a chain on Vortex, but there are plenty of people who have so Im assuming that we just got lucky !
