I love to use flies from friends like Jerry (even though I've not made it to the cabin by the river yet). I like to swap flies with fishing buddies too.I tie 95% of the time. Though I do buy to support a shop when I'm in there asking questions and not already looking to purchase something else. I'll also buy when I'm in a new area. Like when I went out to Yellowstone. I probably bought more flies that trip than I'd purchased in years since tying my own. I've also bought to support Jerry's kids.
