As TTG suggested more demos using the new VH. There are some great new drum kits I'm sure he'll emphasize those but you may want to ask him some to take some extra time demoing them.

You'll never think of the Tyros2 the same way again after you hear and play the Tyros4. And with James Sargeant doing the demo, I'd be surprised you don't place an order with him on the spot. Have fun and good luck
