Tripod Head help needed

I wouldn't make a decision based on one review alone, but according to this review, you should add Feisol and Sirui to your shortlist.

There's no mention of Giottos, but Manfrotto don't do all that well.

I would also aim for something with at least a 38mm/40mm ball head for your setup. The 'maximum load' specified by manufacturers isn't necessarily much of a guide to optimum useability.
