As long as we are discussing "new" material, I will throw in the ring my favorite new material......Berkley Fireline Crystal. I use the 2lb and 4lb test for almost all my leaders. I have gone the mono, floro, and uni route and I have yet to find a longer lasting, better turn over, more versatile leader. I know I am most likely alone on this one because I only know of one other furler that uses Fireline Crystal. I have used 6x tippet to furl and I agree that it makes a very nice leader. My biggest objection is when I snag something (and the way I cast, the fly could end up anywhere) and I have to put a lot of pressure on the leader to break the tippet, the leader comes back in a hyper curled mess due to the stretching. Floro is not as bad as mono but with the firewire, there is no stretch and thus no curling problem. Fireline is expensive but I have some leaders that have lasted 3 seasons. The longer you use them the more supple they become.
