Hook and Hackle has the best prices for a kit 5 weight. Check out their site and if you have any questions call. they are wonderful to talk to. Is it worth it to build your own rod. I think so yes but that is just me. It depends on what you want out of a rod. Cost wise your time is worth something. That being said think about this. You are fly fishing your favorite spiecies with a rod you built yourself, leader you did yourself, and a fly you tied. You catch a fish. How much money would you spend for that. Me that is priceless. We all have our own opinions on building and I hope others express theirs here. My advise GO FOR IT!!!
