I'm sure you're a fine photographer, but to offer another presentation of the importance of a good, solid tripod i'd also read what Thom Hogan (just some professional photographer) says about tripods:

If i had profoundly deep pockets, i suppose i'd buy a Really Right Stuff TVC-33. However, i use a Mamiya RB67 Pro-S which is a bit heavier than a Hassy so my needs are different.... Otherwise, i'm perfectly satisfied with my Feisol CT-3342 carbon-fiber tripod and it holds my RB67 just fine....
