RIO Technical Trout Premier is a fly line designed for picky fish eating small flies at long distances. The line's long, fine front taper encourages delicacy and accuracy and this is a great line to fish with dry flies, nymphs, soft hackles, and emergers. The taper also increases loop control so you can put a small dry fly on a dinner plate at 60+ feet. If you're an avid tailwater angler or find yourself continually fishing to spooky fish, this is a line for you. If you're a fan of RIO's low-stretch technology, check out the Elite version of this line. With RIO Technical Trout, fish will never see you coming.
