nigel i think you advised me to try micro swivels for attaching hooklink to mainline ages ago in a previous thread.
I've been watching some bobb nudd videos recently and he uses them for both waggler fishing and feeder fishing, I just liked the look of them and thought it would be a good way of attaching a lighter hook link to the mainline, I sometimes use a four turn water knot for connecting similar size mono together but I'm not confidentwith that knot when attaching hitech hooklinks and i dont like using loop to loop.
maybe it's number 24 i need not 30 the link that ed provided states that no 30's are equivalent to no10 shot though.
Why use a swivel, they dont actually "swivel" at all under presure,surely a loop to loop would do just as well. I think that swivels, just like so much other manufactured "stuff" is made to catch anglers and not fish.
