Did you see my thread on the X-45 wake? I only have been behind it once, and was the owner's first time out, so it likely needed some adjustment, but was not thrilled with it. You have been behind it and found it to be good? http://www.wakeworld.com/MB/Discus/messages/3183/565176.html?1207659382
The Tige RZ4 and 24Ve have a terrific wake. As was suggested, you need to ride behind them and make a decision that works with your heart. Dealer support will be important if you can't see a difference.
