Our preferred line for chasing Peacock Bass in the Amazon. This two line sizes heavy fly line loads quickly and delivers the biggest flies to the furthest targets. 33.5ft head with a 15ft clear intermediate tip (sink rate of 1.5 IPS) for stealthy presentations. Excellent turnover due to short, powerful head and the slow sink rate gets flies just below the surface. Tropi-Core technology for tropical climates. WF8F/I, WF9F/I & WF10F/I.
