I use them all the time, since i was given one some 5 years ago when i started fluff chucking, i cant stand tapered leaders and dont like making my own tapered ones , too many knots for my liking. ive just started furling my own, and apart from the butt knot and tippet ring its pretty easy

i must admit they are an aquired taste you either love um or hate um, i think you know were i stand

they do give a nice turnover and presentation if you get your tippet lenth right, ive used upto 15ft but thats pushing it abit, about 10ft tippet is good.Rod3 , i think hes called that now? sells his through spiderplus.co.uk, his was the first i used and its still going strong now

They can be made from alsorts off materials , mono, flouro, thread ect sinking ,floating camos and so forth.Well worth getting one to try out to see if it suits you
