Downrigger line in Questions About Trout & Salmon Trolling? Posted August 5, 2021 15 hours ago, risackila said: Good to know. Sounds like the anti flea line is a bit slippery and may release too easily. I’m going with a thick 30 lb (Damyl Tectan) which is supposed to be tough. The Sea Flee line is slippery and it has considerable stretch but I have used it for about 7 or 8 yrs now and it does a good job of shedding flea. The spinys come off just by slapping the line against the water but the fishhook type of flea are a different matter; they accrue like cottonwood on the line and are more difficult to remove when thick.. The Big Game mono 30 lb is also good and I use it for a number of things. Although larger diameter mono and fluoro work better than small diaameter lines with fleas when fleas are very thick or densely distributed they can adhere to anything no matter what the diameter or type of material including 150 and 200 lb test downrigger wire.
