Hi Luke, I have a couple of twisted leaders put away for impoundment Barra but might as well use them for Popping. I was suss on them because the twists apear to reflect light which wouldn't be a problem popping the surface. They must work because of thier popularity at a serious price, you thoughts please.
I like your Midknot, I tried it joining braid main to mono backing 8kg mono/15lb Nitlon [fiddley] and 15kg mono/30lb Nitlon as it lays flat. I used it to join the 30lb to 60lb Jinkai leader and put over the scales to 5kg drag, no problem and looks a good low profile knot but i'll keep a eye on it, I read somewhere you prefer other knots.
Do you also coat this knot in braid friendly glue and burn the leader end ?.
What glue do you prefer ?, I used to use Plio-Bond but cannot find it anywhere [with all the chat I hope you find time to fish] .
I only ever use them for popping, and as you mentioned, it simply ins't a problem as the leader is rarely in the water. I also doubt that the leader would spook more fish when compared to the fishing attracting attention of the lures action. Try making your own, there aren't expensive that way and they are fun to tie.
I do like the Midknot, but as Neil stated, it is not my number 1 for those reasons. I also find that it doesn't bite very well with 130lb+ Tuf Line due to the diameter, could be just me but i reckon i can tie a midknot as quick and correct as some of the top guys. With other thinnner diameter braids, this is not an issue.
Other connections that i like, include obviously the 70 turn bimini twist, or, to form the loop, splicing the braid (hollowcore generally >100lb) and then connecting via loop to loop with twisty or using a Bristol/No-name knot. There is another knot that i like that has been created by a friend, i am in the process of learning to tie and then testing.
I do plan to post this kind of information on the main website and as a sticky here in the forum once we have some good and hard info.
