Do you use any terminal tackle when fishing with a Pop-R or any other topwater lures?

Duo Lock Snap.  No swivel, no split rings.

I use either a Duo Lock Snap or Norman Speed Clip if I anticipate changing lures a lot. If I am fishing around big fish and cover, I just use a loop knot formed from a uni-knot. I don't trust the hardware for heavy use.

I use the duo lock in place of round split rings, (not just top water).  That way you never have to worry about tying your line into the split

I use swivels for poppers, but not for spooks or sammy's I think it takes away from the action.

Norman speed clips are my choice

I never use hardware that didn't come with the bait.  Any issues with action are easily resolved with a Rapala knot.

Swivels have no place here unless you are trolling or fishing live bait in a current.

Hardware= weak link

I have never used any hardware that did not come with the bait.  Like others have said it creates a weak link and also hinders action.  I like the idea of the speed clips but for the above reasons I have never tried them.

Just a regular knot

Use a good, high quality snap.

It isn't a weak link, and it doesn't hurt the action as long as you use the proper size - and on most designs, it helps the action.

Tie some 20 lb mono to a Berkley CrossLock and pull until one breaks.....it won't be the snap.

IMO - just because certain hardware comes with a lure doesn't mean it's the best choice. Manufactures generally go with what's cheapest, and a cheap duolock design is NOT what you want. I've pulled apart some duo-locks with 12 lb. test.

Also - experiment with the use of snap vs. no snap. On crankbaits, it's a no brainer - the proper snap will aid the action. On topwaters, they might put too much weight on the front or certain baits (like small poppers).

FWIW.....I fish crankbaits 90% of the time, and I use a snap 100% of the time, and I've yet to break one.      

by "weak link", I meant an "extra" unnatural element for the fish to spot.

It isn't necessary so why add it?  Speed clips for crankers, I get, anything else, I don't, but to each his own.

Agreed - to each his own.

I like to use a snap in place of any lure that uses a split ring (especially walking topwaters, jerks, cranks, etc..) I've experimented enough with that style of bait to determine that a snap (or split ring) actually aids the action and helps free up the bait.

So in that regard, either a snap (my pref.) or a split ring is a necessary piece of hardware (for me).
