The original spey line, frequently imitated, never bettered. For 2009 the line features RIO�s XS Technology� for an extraordinarily slick, dirt-repelling coating. It has an easy loading head between 45 ft (13.7 m) � 56 ft (17.1 m) (depending on the size) and is the most versatile of all spey lines. The WindCutter II is available in two formats: 1) a full floating line with a welded loop at the front end for attaching RIO�s VersiLeaders to, or 2) a VersiTip line with a body and a selection of 15 ft (4,6 m) tips. These tips are: floating, clear intermediate (1.5 ips, 4 cm/s), DC Type 3 (3 ips, 8 cm/s), DC Type 6 (6 ips, 15 cm/s) and DC Type 8 (8 ips, 20 cm/s) sinking tip and each tip features RIO�s thin, non-hinging welded loops. The WWF 5/6 does not include a Type 8 tip. The 4/5 is only available as a floating line. RIO has improved the VersiTip version for 2009 by removing the middle floating tip (Tip 2) that has been a standard in the past.
