Was recomended to me to place a Swivle before your spinnerbait... this doesnt make sence to me... Anyone know why ?

For an in-line spinner a swivel/snap combo is not a must but by all means, use one !.

For a spinnerbait ? don 't see what 's the point of adding a swivel, spinnerbaits usually don 't rotate on their longitudinal axis ( no line twist ) while in-line spinners do ( lotz and lotz of line twist ).

I find tying the line directly to a spinerbait keeps the line in the bend, where it belongs. With a swivel, the line slides down the arm, on occasion,

messing up your retrieve.  For inlines, I always use a swivel.

Do not use a swivel on a spinnerbait.

Period.  

I use a crosslock type snap on my spinnerbaits. I put a small piece of tubing on the R bend so the snap can't slide up or down the arm. Saves time and so far I haven't noticed any adverse effects.

Ok - I agree with SAM - I never have used a swivle but a buddy i went fishing with SWORE you " HAVE TO USE THEM " I told him he was crazy and lets just say he isnt fishing with me after what happned  Just needed the proof thanks guys.

Give it time and bigger bass you will figure out how much of a bad idea it might be. If that snap works its way up the arm of that spinnerbait you give the fish slack or put the lure at a weird angle. Both mean lost fish. It might also pop the blade off the arm and lost fish and bait. How much of a hurry must you be in that you don't have time to tie a knot? Take the time to tie and retie your knots it is worth the trouble. If it was a closed loop spinnerbait the snap wouldn't slide up but it will help twist the line around your bait on the cast and booger it up. It isn't a great idea to use a snap if it means that you could give the bass an advantage.
