Hi Bushy, I've fished two matches recently where, on the first one I was losing fish on pink bungee, so I changed to black hydro and landed fish for the rest of the match, the week after, same venue, started off with black hydro and lost one after another
. But when I fished my inside line on pink bungee I hardly lost a fish. I have found that certain hooks don't work on certain venues, some fish have softer mouths and a finer hook, ie tubertini, will just rip out, whereas on other venues a thicker hook will not penetrate deep enough to keep hold
For all my worm fishing I would use an 'animal' 14's/16's, but when I had a club match at woodlands view I lost every fish til I changed to a Drennan superspade.
Most of me commercial fishing is done with the superspade or colmic 501. I struggle finding a spade hook that will take a large diameter line, I'm not a lover of eyed hooks unless hair rigging.
But back to your question, I think it's just about testing and getting the right balance of elastic and hook that works on that venue, because evn though you are fishing for the same breed of fish, their feeding habits, skin texture will be different.
I know this hasn't helped much but these are just my expereinces of the differences of hooks and elastics on different venues
