Extra purchases might include a sailing rudder even if you aren't planning on purchasing the sailing kit. The sailing rudder, which is cheap and easy to install, is larger and hence gives much better handling in all conditions, with or without a sail. Many on this forum have said the same thing. I also bought the turbo fins for both sets of mirage drives and like them better than the standard fins.
You are sure to have a lot of pleasure if you buy an i14T. Good luck and have fun!
