Based on the same technology as the incredible Sixth Sense flylines, Airflo have created a small range of flylines that sink in a U shape profile. With the recent popularity of the 'washing line' technique, we realised that creating a U shape retrieve path actually allows the fly to fish through a range of depths effectively, during a single cast. The Airflo Sweep Fly Lines follow this U sink path by increasing the sink speed of the belly section of the flyline to be faster than the tip & running line. The use of power core, reduces tangles significantly & helps sets the hooks despite the belly in the line, something that was always a problem with the old Hi-D type lines. Airflo Sweep Fly Lines are not the line for early season when fish are hugging the bottom, but as a searching line when the fish are moving up & down throughout the water column, it is an extremely effective line. When boat fishing, the Airflo Sweep Fly Line creates a far sharper angle on the final lift & this almost vertical action is extremely deadly for strip & hang techniques. Available in Di 5 & and Di 7 belly sink rates, the tip of the Di 5 sinks at 3.5" per sec & the Belly sinks at 5" per sec, on the Di 7 version the tip sinks at 5" per sec & the belly sinks at 7" per second. All lines are 35yds long, you'll need it!! Available in AFTM 7, 8, 9 Di 5: 7XS-SW-WF (size)S5-PG Di 7: 7XS-SW-WF (size)S7-BK
