What it is Hareline Veevus Thread is a fly tying thread made from gelspun polyethylene (GSP). It lays in a flat profile with low bulk buildup, and it’s slick on the hook compared to many standard threads. For its diameter it’s very strong, which is why a lot of tyers reach for it when they want to pull hard without breaking thread. What to tie with it Use it for any job where you need high tension: spinning deer hair, stacking deer hair, and really cinching down synthetic materials so they don’t roll. It’s also a good choice for locking dumbbell eyes in place and for building more thread protection in patterns meant for toothy fish. It still works as an everyday tying thread, you just need to account for the slippery feel when you’re finishing and securing materials. Flies and the fish they're for On a Dahlberg Diver, Veevus GSP makes the deer hair work easier because you can pack and torque down hard; that fly is a staple for largemouth and smallmouth bass on topwater, and it also gets used for pike in weedy lakes. In a Flash Tail, the strength helps when you’re stacking and binding hair and synthetic flash for baitfish profiles, a common streamer approach for bass and other freshwater predators. For a Clouser Minnow, it’s a solid thread choice for cinching dumbbell eyes and locking materials down tight, and that pattern is routinely fished for smallmouth, stripers, and redfish in rivers, lakes, and coastal water. How it compares Compared with UNI Thread, it’s flatter, slipperier, and stronger for its size, but it comes in fewer options.
