My understanding is that snap swivels are better than tying directly because they allow the lure to wiggle freely as it is retieved or trolled through the water. A loop of a Rapala knot seems to offer the same room in theory, but the loop closes once you start to retrieve or troll--the metal loop of a snap swivel remains an open loop. I tied directly for years and had better results in salt water (I fish 4-1/2"-5" original Rapaplas for schoolie stripers--deadly) than in fresh. Recently I started using snap swivels trolling Rapalas for trout in fresh water (late season tactic) and found it it works great. I had two nice rainbows and four pickerel, including one giant that broke off right at the boat--his teeth cut the leader when he turned his head--on my last trip of the season last week. Nice productive day for end of season fishing here in CT.

I hear ya ranger. Same here
I fish flash green braid with a fluoro leader on 100% of my rigs.
Favorite braid is seaguar smackdown.
Power pro super 8 green works ok But it fades pretty quick . Seaguar invisX or AbrazX is my go to fluoro
The flash green shows up good using polarized glasses.

I tried white line one time and it worked but I just couldn’t get used to white line.
High vis yellow would probably work too but can’t bring myself to go there.

Had a white rod one time. Gave it away to my brother because I just couldn’t get used to a white rod.

I’m kinda stuck in my ways.
