I'm exactly the same, my Gitzo is 57.5" which is perfect for me, and the only RRS tripod I could buy is the TVC-33 which has a max height of 58.0". I figured all that out when I was buying mine two years ago. Good luck with your new tripod, I'm sure you'll find it a pleasure to use. Both these brands make great products and it's hard to go wrong with either.
BTW, it's just the parts side of Gitzo that sucks, the service side (repairs and such) is very responsive. Given that though, it can be infuriating if you need a spare part and they're useless. I learned that lesson this year myself. Apparently the problem is local to this side of the pond, in Europe the service is excellent. Hopefully Manfrotto Distribution will fix the parts problem over here.
