This is the Teeny - TS250 . That is , the salt water version. A fine sinkingline for the seabass and other species ofcourse if you have to go deep at sea, rivers or reservoirs . In the States and Canada they use this line often for salmon in the river. The first is sinking 30ft and 70ft remaining are floating . This line has a sinking-rate of 6.0 ips and is suitable for rods from Aftma # 7 t / m # 9. (Especially the last 2 !)
