I just bought a Gitzo GT3541LS (no center column) and a Markins Q20 ballhead. I have screwed down the ballhead to the tripod base as best I can. At first I tightened the set screw from the bottom of the tripod base to the bottom of the ballhead and then the ballhead wouldn't pan. I found on the internet (not on Markins instructions) that I should not use the tripod's set screws as it may mess up the pan head. As soon I loosened the set screw, the Markins Q20 panned correctly.
Now on my first outing with the combination, I find that the ballhead loosens and turns on the tripod base. Naturally, that concerns me that the ballhead may loosen all the way and my D800 would hit the ground. Any suggestions to better secure the ballhead on the tripod without using the set screw on the tripod head would be welcome.
So far I like the tripod -- a good height for me and folds up fairly compactly for its size. Waiting on delivery of leg pads for ease in carrying. I was surprised that Markins did not include installation instructions that mentioned not using the tripod set screw if that is important, and apparently it is! MauiKane
We say there: If you are using a Manfrotto tripod,or one of the most recent versions of a Gitzo Systematic tripod with “Lock Screw”, for your Markins Ball Head, don’t use the screws under the base plate, because they may hinder the free movement of the panning base of your new ball head and even distort it.

Thanks JRP -- I have never seen the document/instruction sheet you referred to in your message. At any rate, got the Q20 secured, I think, so it won't loosen easily. Tom
Somehow in all these years I missed hearing not to use the tripod set screw. I have two Markins Q(M)20 ballheads and have used the set screw with no obvious problems with the panning head. Of course I don't torque down the set screw with all my might.
