Typical, of mine anyway. They tend to get top-heavy because they run out of climbing room and therefore the vines, which keep on growing, start tumbling all over each other near the top.

But it is a glorious top-heavy when in full bloom.

It can have its good side. A non-gardening neighbor of mine (who couldn't see the thin vines down near the base) used to marvel at how I could "magically" grow flowers up in the air near the top of the fence. LOL

I agree with Kate that they tend to be top-heavy, however this is mitigated by how you prune them and how you train them along the fence. I still would not use "uniform" to describe their appearance but if you look at some of the pictures in this forum, you can see that they can be a glorious floral display if that is important to you. More so than any other vines I can think of.
