Re: Tying on lures
Depends on several things.
Some lures have different action with even a small ball bearing crosslock or coastlock and I will not use any other snap swivel. Those I tie on with a uniknot. Small floating Rapalas always get tied on.
I use a fly snap on most small, light lures.
Anything that requires a bite-proof leader (big, heavy snake and musky lures) gets one made up from titanium multistrand with a coastlock snap swivel backed up with about 50# shock leader.
Bottom line: NEVER use any snap other than a crosslock or coastlock and always use a BB swivel if you can. Like dingbat says, the others open too easily.
