In the early 90’s I was guiding around 150 days a year and needed a big search nymph that might help those who struggled casting to catch a fish or two! 
Here we are 15 years or so later and its the biggest selling fly in New Zealand. 
With over 18000 101’s per year getting shipped worldwide the volume of sales speaks for itself. 
 
Price per 12 - excluding gst.
 
Hook sizes: 8, 10, 12
