Berkley Vanish® Fluorocarbon Fishing Line, Clear, 4 lb Test Strength, 250 yd

I re-spool this stuff on a Pony spool so it fits nicely in my fly fishing vests. Only use it as tippet material on my leaders. Still using the traditional fly fishing standard leaders but Vanish has been a stellar addition to my arsenal. One of our club members (Thank you Mr. Palmer) introduced me to it many years ago and it's been my go to ever since.

Vanish is the most cost effective way to build long fluorocarbon leaders. Here in the Keys we use LONG leaders for mutton snapper when fishing in deep water. I like 24 foot 60 lb. leaders and I know of others who tie longer than that. Without the bulk spools of Vanish my leader costs would be several times that. for lighter tackle fishing on the reef I spool entirely with 30 lb vanish and use knocker rigs to avoid having to tie separate leaders.
