From my limited experience on the Vandy (a pair of double dips) I'd say the current is the biggest concern there provided you're not going deep or penetrating the interior.
My first time I made the mistake of bringing along a friend from CA who only had her OW cert but had a lot of dives in as a volunteer diver for REEF. My plan was to take her on a West Palm drift dive and evaluate how well she did, then two days later do the Vandy. Well, the West Palm dive we scheduled for 4th of July 2013, when conditions were pretty much defined as "King Neptune throwing a fit." That dive got canceled, so my first observation of her skills was on the Vandy. She didn't have a nitrox cert, so we were both on regular air. I played it conservative - 80 ft planned max depth, 90 ft contingency, swim into the current at the start, head back towards the mooring at 1500 psi. Good thing I did that. According to the DM there was a ~1.5-knot current running and it was a little rough topside; she torched through her air and I imagine we only had about 12-15 minutes on each dive before having to call bingo. I could tell that she was not prepared for the current. If you're not used to fighting a current the Vandy can be a rude awakening on some days.
