I get the Leeda Selecta cast, 15 ft tapered leaders from Sportfish, I can use the same one on my line for a very long time, certainly all season, I'm retired and I fish very regular, never get a tangle or a break, I usually fish with a 3lb tippet, I do renew that pretty often "Sight free flourocarbon" I use Roman Moser tippet rings, wonderful things, saves a lot of messing about, I'm talking stillwater here, on rivers I use mrtrout's furled leaders, fantastic weapons hope this is of some help to you, Cheers...........
