There's a lot of chatter and hard decisions being made between the two smaller Markins ballheads, and compatibility with the Gitzo traveller and GT2531 tripods, and the differences between these also. Seeing as how I'm now a proud owner of all of these (needed another tripod set for the hubby....) I figured I'd post some pics to help those choosing to decide.
In terms of compatibility of both ballheads and the GT1541T, I find the legs fold up about the same for each ballhead, the limiting factors are the nobs, not the panning base on the older Markins (Q3 Emille). The sexy red ballhead below is the older Q3 ballhead, the black one is the Q3T.
The big difference between the two tripods is the bottom leg diameter, the standing full height, and the fold up length. My 6" husband has to bend to use the traveller tripod fully extended, and the GT2531 is much more solid, all the way to the ground (all leg sections extended). But it doesn't fit into my day pack. Take into account here that I've removed the GT2531 center column (my husband doesn't need to bend to use this pod w center column extended), cause I use it lots for macro, and it gets in the way - I'm short also.
