But... have you lost the yellow spongy thing a million times yet? I finally broke down and bought the bracket for the aero bottle. It was the best money I've spent. No more rubber bands holding it in and flinging off at inappropriate times. And no more yellow spongy thing either- I bought a loofah at the dollar tree.

And you'll probably be fine with your strap in the water. My Nike does just fine when wet. Gotta keep an eye on that HR and keep it down to avoid pushing too hard. After 3 years of tri racing, I still don't have a good gauge of where I'm at if I don't have it on. Some days I feel like I'm going at it too hard and my HR is 130, some days I feel like I've got more to give and my HR is 180. I'd be lost without that HR info. Go figure.
