I have tried almost every flouro made and have the best luck with P-line 8lb 100% flouro. I just put a spool of Seagar INVIZ 8 lb on a new Catalyst I bought and so far am having good luck with it. It does not twist up like the Vanish and BPS flouro. I do use the KVD line conditioner and I believe it makes a big difference in more than one way. I will say that if you are using it on a spinning reel, it is very important that you place it on the spool correctly or it will loop up and be a huge headache.
