Thanks Dave,
I've look at the black magic one, it actually "looks" awkward in use on youtube and the like. Defiantly something to try
I can see that it allows you to sit in it to put weight on the fish so to speak. Im sure it is better in that scene but looks un-natural my thinking is if you have to think about it your probably not going to get the benefit.
I was looking at this one from ottos
Sit in type from blackmagic
Similar principle i found on line, then i get a separate Gimbal
Hmmm might do a lunchtime walk up to compleat angler see what they have on the shelf for a tough and feel
