I like tying my own Euro leaders but it's always fun to try new gear. Out of the 3 popular brands of pre-made French leaders, the Dohiku is my favorite. It has the least amount of memory of the 3, especially when treated with KVD Line & Lure conditioner. On a large arbor reel, it resists coils the best out of the 3. Casts flies easily and accurately, especially on a 10' 2wt. Paired with 18" of 2x sighter, it is extremely sensitive when properly tight-line (straight line to water, zero slack in the line), it makes for a very sensitive line for even subtle takes. Because the front taper is thin,it's easy to keep a lot of line off the water and tight to your flies. No knots or sounds going through the guides like home-tied. If you don't tie your own leaders or just want to try a new technique, this would be the French leader to buy 1st.
