Traditional Spey lines usually have much longer heads than the more popular Skagit and Scandi designs, and require a little more casting skill and experience to handle. The advantage with these longer head Spey lines is that there is less stripping in of the fly after each cast (more fishing time) and it generally makes anglers better Spey casters with use. However, the longer the head length of the line, the better the caster needs to be, the longer the rod length should be and the amount of room required behind the caster to make a cast ideally should be greater too.
RIO offers three types of traditional Spey lines, covering the spectrum for all abilities of angler and for all fishing situations, in order of ascending head length . Rio Short Head Spey . Rio UniSpey . Rio PowerSpey
