Just like a fine suit some things are made to measure

Just to explain out of necessity i have to use a very long leader, some fly lines dont turn over the leader so a bit of DIY is needed.
Most fly lines have different tapers and other qualities (colour,floatablity etc).
The perfect line for me would be WF with a very long belly and an aggressive front taper so on some lines i simply cut off a portion of the front taper to suit my needs. Just make sure you super glue the end before attaching the nail knot or braided loop otherwise water will penetrate the core and you will have a sinker.
