Looks like we lost morlin, I guess he is overseas dreaming about his new 600, sigh. oh well, doesn't stop us from yammering.
Haha. Actually I was sleeping a bit. I live in Sweden.
Really good suggestions from you all. Will look into most of them. The stuff from RRS seems so good but not sure if there is a way to get them except buying directly from them when you live in Sweden. With taxes and transport costs and all it will be expensive. The difference in cost is HUGE between gear in the US and here. It would be less expensive for me to fly over and spend a weekend in New York, buying the 600mm and take it with me home than purchase it directly from a store here.
The replacement foot from RRS will be bought.
Someone else who has suggestions for the gimbal head. If I should go with the sidemount or not? Seems like a good choice to me with less moving parts.
Guess I need to sell my car soon also =) But the car is not good in the forrest anyway so why don´t get a donkey instead and spend the rest on more gear? =)
There is no question that a complete package from Really Right Stuff would fulfill all your requirements. But since you're Swedish, you share the same problem as I have, being Norwegian. RRS is not sold here. You would have to pay both transport and VAT, which makes it a very expensive solution. But if you know anyone who can pick up the stuff for you in the US, I would strongly recommend them.
I use the Gitzo GT3542LS tripod, with Winberley Gimbal II, a combination I am happy with, even though some say the 3-series isn't sturdy enough. That is not my experience. I have used it with a 600 f4L IS II, 2xIII extender and a 7D body. That is equivalent to 1920mm. How tall the tripod needs to be is of course something you should pay some attention to. I am 183cm tall and I have not felt the need for the XLS version of the tripod, even when I shoot birds in the air or in trees.
A good point regarding the head, as Neuro pointed out, is that the RRS side mount packs very efficiently, whereas the Wimberley is a substantial chunk of metal. When you hike in the area around Kebnekaise and there about, you'll be happy for every gram and cm3 you can save. Even though I have the Wimberley, I am thinking of getting the RRS.
A good leveling base is essential when you use a gimbal head. That saves you a lot of time during set up on uneaven ground. I have not found anything that competes with the RRS bases, so again, look for a friend in the US. Or alternatively, go there anb buy everything yourself. The cost saving will pay for business class airfare and a stay at Waldorf Astoria for a week
Good luck and I hope you have a decent budget, because you have entered the really expensive side of your hobby
