I have both and with my GH2 i use the gorilla pod. It supports the weight just fine, is much easier to maneuver into tricky positions such as spread across/in between rocks. You can not use your Nauticam tray with the xit tripod, with the screws/fixings provided, they are not long enough. So you have to attach your arms for your lights to the tray. Re positioning them every time you move the tripod, Which is way too much hassle for me.
If you want to buy a xit tripod with legs i will sell mine to you, i've only used it twice.
