I just received my 300 2.8 IS II. Mounted with my gripped 5DIII and 2x TC III the weight feels like it is too much for my current Manfrotto ball head and tripod. I'm looking at getting a new tripod and gimbal head. The gimbal I am looking at is a RRS PG-02 FG. For legs I am looking at a Gitzo GT3541L series. Currently Gitzo is running a rebate at B&H for $200 on this tripod. I'm wondering if anyone has any input or ideas if this would be a good combination? Surprisingly there are not many reviews on YouTube for this tripod. Just some headless guy? with white gloves extending the legs, but I don't think that is much of a review. LoL
