i use a benro c197n6 (carbon fibre, there is a much cheaper aluminium version), it has excellent features for positioning the center column in strange macro positions (variable angle, not just horizontal), and it also has 3 angles for the (independent) legs. i like it a lot so far. it has twist loks, but they are big and rubbery, and need only about 1/4-1/2 of a turn to go from locked to unlocked and reverse, it's alos nice that you don't really need to lock the legs when storing/carrying the tripod, as they won't open freely as with most flip-lock tripods. both fliplocks and twist locks have their disadvantages and advantages, i am used to both, and i like both. i tend to shoot in the winter, in snow and cold (high altitude), and i find twist locks a lot easier to handle with big thick gloves than flip locks (not sure if that means anything to you though)
the advantage of the benro is that it's well built, while relatively cheap. no idea how much it will last though, but looking good so far.
for the head, even though it may sound a bit opposed to what you mentioned, i suggest you try to play with something relatively big and with friction control: it will mean you will have a bit of trouble to set it when you start (because most of them have knobs), but once you set it up, you will hardly need to touch the knobs unless you change the lens (weight changes) or the angle is changed a lot (more expensive elliptical heads will handle changes in angle too, mine does not, but it's more expensive version does, i hear). i use the friction control a lot, eventhough paranoia pushes me to lock the ball almost every time
, but i would not imagine working without this feature now. my head is a benro ks-2, there are cheaper/smaller versions, there are also more expensive (elyptical) versions, i think kj-x is one such model; most will recommned going with arca swiss, really right stuff, kirk, or markins for that kind of head though (if the higher price is not an issue, i agree it is probably worth it). though there are disadvantages, i think the benefit of being able to take your hand off the camera at any time with no worries thanks to the friction control might outweigh the rest (but you really have to try it out for a day of shooting and see)
good luck finding the best solution
edit: my benro described above looks like a (decent) copy of the giottos linked by you. some of the details are amazingly similar
. they also claim dust/water proof (not entirely true, but there is some attempt at it, i admit)
