Continuing my quest to find a lightweight tripod head to match to a Gitzo 1541 Traveller tripod.
So far, I've been looking at the 3 options in the title. Main interest is use in backpacking, so weight is a concern. But it should also be able to handle up to a 7D + 100-400mm lens (~5.5 lb). And I want something of good quality/build. I don't want to be buying a second head in a year.
The Q3 Traveller gets a lot of recommendations on this forum. However, I'm in Canada and can't seem to find it locally. I could order it from Markins, but then have to incur shipping across the border. Price-wise, it's in the middle @ $320 CAD (per their site) and weight-wise as well (375g).
The Benro B-1 B is available locally listed at $190 CAD and also weighs the least (360g). So right off the bat it seems ideal in both categories, provided it's quality is up to par. It does lack the Panorama Index Q3, but I can live without it. FWIW, I have read some negative comments about Benro heads, but only in relation to the BH-series. All comments I could find from B-1 owners were positive.
And finally, the Acratech GV2 which is both the most expensive (list $400 CAD locally) and heaviest (450g). It will apparently function as a Gimble head, but with a 100-400mm lens somehow I don't think that will work very well. 
Right now I'm leaning towards the Benro B-1 B, unless I hear reasons not to. Any and all suggestions welcome!
