Interesting Rob....... but I do think Marc is right about the way to achieve outright distance and this.....
No argument about distance at all. However, a Switch rod is a liability on rocks and for me, does not have the backbone required to stop angry Pollock diving. However, something like a Beulah Opal that is designed to be over head cast and is built for stopping angry fish may be far more suitable...if I could get one in the UK.
No argument at all regarding double handers (not switch) on an open beach and big waves.
As to finding Pollock, they are a structure fish, not an open water species. They like rocks and kelp so it you are putting a fly 150' out into open water, you are missing them. If, however, there is a kelp bed 15 feet down, then of course, I would fish over that, but as a rule, the fish are in under your feet.
