i don't, but if you can feel reasonably ready for the feb test, I'd suggest taking it in February. First, you get a real feeling for how the test is and the stress associated. Second, you can cancel it if you need to... or if you don't and you don't do so hot, you can retake in June and still be way ahead of the cycle.
I just think that taking in Feb gives you a few more options
The cost of canceling your score increases the later you take the test. Canceling in Feb is no big deal, the cost for canceling in June is a little higher because it means you'll be rushing apps out after you take the October test although you'll still be pretty well placed in the cycle. Canceling the Sept test puts you behind in the cycle. And canceling the Dec test pretty much puts you out of the cycle altogether.
