While some people don't like it, I have had good results with the limpest line that Berkley offers, Maxima and Vanish for Fluro.
There are times when I'll have to flip flop the parent spool to keep the twist out of the line, and I also watch very closely what the lure is doing to the line. I have no faith in the quality ball bearing snap swivels to keep line twist out, so I rarely use them. It's something that I've lived with forever.
Ken, you are doing about everything you can to get the twists out, with the exception of dragging it behind a boat without anything on the line, including a snap or snap swivel to get the twists out.
If the line, when spooled on the reel, still keeps it's memory, then it's not new enough and will be a constant PITA to use.
