I use one of these
1/2" Yacht Braid Leads & Lunge Lines by Sunset Halters
10 foot, brass swivel snap. (Add me to the list of those who can't manage bull snaps, especially after they get a little dirt in them)
I find it perfect for my use.
It's short enough to keep control, long enough to tie around something large or to reach around behind me for that perfect smack with the built-in popper.
The loop at the top makes it easy to replace the snap when (not if) it gets broken, stuck closed, etc.
It's comfortable to hold.
Costs more, but it's worth it to me.
