If I had to guess, I'd suspect it's for practice casting. For example: http://swiftflyfishing.com/products/hi-viz-practice-fly-lineI hope this is the right place to post this. I found a crystal river 4-5 fly combo at a sporting good big box store that is closing.in Houston Texas I picked it up for 20.00 bucks new in the box . 8'- 8 section rod with a Model CR -4/5 reel. Has a little fly box, leader 9' of 4x and and something they are calling toying line 20 LB. 15 Yds. White. I have looked the internet inside and out and can not find Toying line. Does anyone know what toying line is? I do not think it is backing or fly line being only 15 yds . It feel like speaker wire without the wire inside, and it is solid. Thanks so much.
All fish must be caught once in their life to show them who is boss
But again, only a guess.
