hey simon, heres the thing. in you are referring to a real snap like a saltwater type it will affect the motion because it is bigger and heavier than the original split ring. if you are referring to the normans speed clips then throw them away unless you are using them to catch bluegill.
keep in mind that bass generally dont feel like coming into your boat or your hand. they tend to fight being cought. in that fight bass and most other fish will twist and jerk and pull and jump and wrap you up and all sorts of other things. when these things happen the bass can actually pry open some clips and unhang itself. thereby causing you to not only lose a fish, but a 5 dollar plug in the process :'(
