to snap or not to snap

[RIJIMMY]

I was just rummaging around teh SWE webs site and came upon an article by Steve McKenna about artificials.
I noted the following
"Furthermore, I would strongly recommend connecting your running line to shocker with a high quality ball bearing barrel swivel (color-black). This will prevent line twist which which can be a nightmare, particularly with spinning outfits. Also, at the other end of the shocker trace, tie on a top shelf snap, also in color black. This will aid in chnging lures and will provide added action to your artificials."

I tie a bunch of leaders with just a barrel swivel and always tie direct, unless using a spook. I've always beleived that the snap would deter a fish from hitting the lure, perhaps that is stupid since the big trebles hanging off the lure do not affect them. So, if its good for Steve, it must be ok. Its just going to bug me if I do it and confidence in your offering is a big part of it for me, what do others do?
