A few weeks ago I was inquiring about tripods for medium format. After some additional research, I've concluded that I might as well just spend the money on a Gitzo since they are essentially un-contended in quality and longevity. I really do wish there was a cheaper competitor, but there doesn't seem to be. So now I'd like some input on which Gitzo I should specifically go for. Currently I'm mainly using a Nikon FE2, but will be buying a Hasselblad 500cm with lenses up to 150mm ASAP. Should I go with the Mountaineer GT-2531? Or something more sturdy in the 3531?

Thanks!
