i used to get alot of tangles or wind knots ,i,ve found using 20 or 30 to be less prone to wind knots and always use ball bearing swivells if i,m spinning ,i bait fish with braid and have never had a wind knot on a fixed spool used for this alone so i recon its the lure,s spinning or maybe the lure twisting during casting that causes it ,what reel are you using maybe its not helping either?
i put the braid through my swivel eye twice then do a tucked half blood knot with ten turns

you can double the braid if you want but i never had a prob with the above
