I compared the GItzo 1550T, the 1540 and the 1541. In the end, I bought the Induro C014T. I never thought I'd say that after seeing the Gitzo's, but honestly, I was very impressed with the quality, sturdiness, compactness and light weight. I set up all of those side by side in the store and actually liked the Induro best. As I said, I was quite surprised as money wasnt the real issue for me (having said that, the Induro was half the price of the Gitzo's).
It handles my Rollei 6008 Integral 2 with ease, which is heavier than your Hassy.
