When I pull 2 dropper loops together I don't like them to be able to lock up on each other. I like about 5" of space between the loops when pulled at each other. I now secure the hooks onto the loop with a Palomar. Keeps the hook on the loop without any slack that can get caught onto the eye of the hooking causing break off. Misuse taught me something.
That's about it. 4 spread apart. I like about a 10' top shot the rest spectra. I do not use straight spectra because spectra has poor abrasion resistance and does not hold up well rubbing on rocks.
I use big mustad hooks.
