What is a good way connecting braid to a fluoro leader and the weight and hook ?
Couple of ways; a #12 swivel(per Earnest Paty) or a double uni knot which isn't always easy to tie in a boat in the wind.
For a weight I crimp on a buck shot 1/8 or two about a foot to 18 inches above the hook.
I almost always use a Palomar or a uni loop on a hook.
The reason I like my weights that far above a minnow hook is to use the weight(s) to drop to get a snagged hook loose.
