Rob, are you saying that you're splicing the hollow core braid to form a loop instead of tying a bimimi? It''s good if you can do this. A few GT anglers do this and there are some who go the the extent of splicing the hollow core to kevlar cord.
Hi Brandon
I only tie a bimini in my main line as per normal... then attach it to the loop already in the wind-on leader.
The wind-on leaders are made exactly the same way as Game leaders,ie, TOPSHOT/Geoff Wilson method... but I use stronger/thinner JB hollow core instead of dacron.
I splice(with half-hitches to make that nice spiral) the end where the Mono enters the Braid with 30lb braid and coat it with Dac Tac.
What you're left with is a very slim-neat-strong leader that is easy to attach or remove to the bimini.
I've made about 20 of them, so am still perfecting the art... but my friends love them... and keep taking them off me... so I'll get plenty of practice
The only draw back is they take a while to make... but I've got the process to just under an hour now, so it's not too bad... plus it gets me through night-shift at work (shhhhhh)
I'm about to make up anoth batch and can post a pic of the finished product if you like?
