The Streamer Max from Airflo is a great sink tip line that will really turn over heavy flies. It uses an extremely aggressive taper to easily load rods and to make turning over heavy flies a breeze and with the Ridged running line casts zip through the guides. These lines are overweighted so do very well with fast action rods.
Chose between the short which is 18′ tip and the long which is 30′.
