Road Wheels & Road Wheel Recommendations?

So, having spent some of Christmas riding H Plus Son Archetype rims around Yorkshire and Kent, I now have what sounds like quite a lot of water sloshing around the 'aero' section of the rim.

I've got the same thing happening. With mine it's been dripping out through the nipples and leaving puddles in the kitchen. I'm guessing that the water is getting in through small gaps between the nipples and the rims.

I'm going to try your approach of small holes in the rim tape, but you're right it doesn't seem like an ideal solution.
