When I had a Linhof TK45 I used a heavy alum Gitzo tripod and a 1570 mag head. It was more than enough with such a big base.
When I moved to 8x10 and 7x17 I needed the big Ries tripod and head. I tried the j600 and 250 double tilt on my 8x10 light weight Phillips, but it was always a little shakey. Now I have big Ries tripod and base under each You got to have the pieces parts for stability.
Some times you just have to wait a little longer to get what you want. I'm only 74.
