Kippy, I use the larger of the two sizes. Most of mine I rig with 3 weights like Steve showed me. I did a couple with 5 weights, but the 3 weight ones wiggled a little better.
I was never able to rig slug-go's correctly with the classic worm-style hooks. I always found that no matter how perfectly straight they were before the cast, the force of casting the lure would slide the body down the hook and cause the rig to spin. Until I started double-hook rigging, I would simply use an 8/0 mustad straight hook in the nose with thread wrapped around the shank. It wiggles just as good as the double hook rig. I'm not really sure why I have switched to double hooking them to be honest...
Here is a write up on the style I was using:
