Sorry, I forgot which model I tried, but the point is...
I had a 352RC head... and I wanted to get a Slik PRO CF model... got one (can't remember the model) and fit the head on... and only to find out, the screw is too long for the head... unlike Gitzo tripods, the head screw can't be adjusted in length, so either u have to sand it off somehow, or get it changed, which was what I did...
i did tried it on another 352RC at Cathay and result was the same... so changed it for Gitzo one... SIGH...:dunno:
