Sagittarius/Capricorn and Aquarius/Pisces

Hello, my friend is a Sagittarius/Capricorn cusp, we've been good friends for about 3 months now, and we naturally get along very well. As you can probably gather from the title, I am an Aquarius/Pisces. I've had my eye on her ever since we started going to school together, and is generally confident that she also likes me back. I am wondering what is the compatibility between our two cusps are.

The reason am I asking is because although we got along like we've known each other our entire lives is because I am a little uncertain about her, she has a good head on her shoulders, and is very lady-like and polite, with a good sense of humor. She also seems to be blunt, and even bashful at times.

Basically, I plan on asking her out early in the month of January next year. So if she says yes, and the first date goes over nicely. I am wondering if in the end, it would have all been in vain, or if there is a decent chance of it working out in the long run.

LOL man you asking me to predict the future ^.^

Lol! I'm sorry. I should have worded what I was asking for better.

I was asking for personal experiences. Or if someone knew anything about how a relationship between the two cusps usually turn out. I was surprised by the lack of information concerning the compatibility between cusps. That's why I decided to ask here if anyone knew anything.
