From Nov 2011
When I was introduced to a Triangle Taper Nymph line getting hold of them in this country wasn't easy and in desperation I phoned Royal Wulff and had a couple sent from the States.
It was well worth the hassle as they are a stunning line to use with a stiff rod. The head section is heavy and the line zings through the guides. The line is a bright, but not fluorescent, yellow and easily seen on a dull day.
I bought the lines to use, primarily, when spey casting a single handed rod, and it fits the bill perfectly. I've tried several lines but the TTNF (Triangle Taper Nymph Floating) is the best line I've found for this application. Now this is a heavy line and a 6wt is well over the AFTM weight convention, I have no problem with this as the weight and its distribution is ideal for roll casts and spey casts. However when overhead casting there is a need to compensate accordingly. Be aware of the head weight and short rear taper or else you could find the line dropping too low in the back cast .
