I've used manfrotto 680B (cheap, indestructible) and a gitzo 5541T (expensive, amazing) for far more than 2.7kg, more like 6kg. I was very happy with the manfrotto but I wanted less weight, more max carrying power, and something that packed real short for travel. The Gitzo ticked all those boxes.
I reckon the Manfrotto (ebay, 20 quid if you're lucky) will be just the ticket.
