when you are using a carolina rig, will the swivells mess up the guides on your rod. if so do you just stop reeling in when the swivell is near your first guide and cast with the 3 or 4 foot after the swivell hanging still?

SH, I think you're missing a key component here. There is a bullet or sliding weight between the swivel and the rod tip.

So don't worry about reeling the swivel through the rod tip.

thanks and my mistake for such a dumb question haha

The weight will do just as much damage to your tip top and a swivel, so be careful not to reel it up too far.  A plastic bead before the barrel weight offers some slight insurance.

how do you guys tie a leader on to braid line... is a swivel the only way.  I want to use briad for my jig/t-rig setup but figured it be good to add flourocarbon leader to it and thats why i was asking about the swivell hitting the guides.  do you just use a leader knot
