Replying to Girls: ponytail hole in a helmet - opinions?

Whenever I have long hair, what I do with it in the winter is always an issue. A friend of mine made me a hat with a pony hole and I love it, but I'm wondering if I'd like the same thing in a helmet.

I found this one, and I like the look of it, but I'm curious to hear what you guys think of pony holes if you've tried them:

Thanks!
