I own a Ries A100 with double tilt head, J100 with double tilt head and a Leitz Tiltall. The A100 is for my Sinar P and Wehman 8x10. The J100 is for my Wehman out in the field and my Tachihara 4x5. The Tiltall is for my Crown Graphic, Hasselblad, and DSLR. I mostly shoot the Blad and DSLR handheld though.
It sounds like a lot of money invested in tripods but I purchased them all used and just about stole the A100 on Ebay. The J100 I paid a fair market price and Tiltalls are just dirt cheap.
