They cover practical line recommendations for specific fisheries, temperature and taper considerations, line maintenance tips, and why choosing the right line can transform your casting and fishing.     Connect with Red's : Email: [email protected] Phone: (509) 933-2300 Instagram Fly Tying: / redsflyshop_tying Instagram: / redsflyshop Facebook: / redsflyshop Shop Online: https://www.redsflyfishing.com
