Well you may have had something else in mind when you devised your loop thingy. However, it sure works good to attach leaders as well. The monocore covering cannot help bit make the loop strong and give it some abrasion resistance. I sure like it
There is also the Lefty's whipped loop. I have several lines with that have a whipped loop & they work good. Google up Lefty's whipped loop & there is a bunch of stuff you can read.
