Hi all
I have decided to pick up a leveling base for my Gitzo, and I was trying to decide among the following bases on others experience, since there is no way for me to try them out (our local store doesn't carry any of these):
1. RRS TA-2-LB: I believe it is compatible with the Series 2 Mountaineers and the advantage is that I can connect this directly to my center column, so it doesn't have an additional part. Anyone used this one directly on a Gitzo, especially with the ground level set (no center column)?
2. FLM LB-15: This is an unknown brand so far to me. But it is German-made, and that means a lot!

And it is cheaper and low-profile. Anyone used this one?
3. Sunwayfoto DYH-66i: Cheaper and some good reviews of the newer version leveling base. However, since I shall have this on all the time, ergonomics is really important to me, and I am not sure about this one. This is a distant third choice for me. I also heard something about tripod studs longer than 6mm being an issue, is that true?
I shall appreciate any input on the ones above or any I haven't mentioned. Thanks!
