Rains,without doubt,fishing over 10ft is better and much easier with a slider,former world champion Alan Scotthorne uses the Drennan swivel float adaptor,which i would use with lines above 5lb b.s.,but the best thing ive ever used is the seymo silicon slider adaptor(if thats what its called),its amazing,i find that i can use wagglers(any,loaded or unloaded)from 2aa up with no problems,tangling or sticking when sliding,my preference for shotting is a bulk,where i let the float sit when casting and one or two droppers,but if fishing for the larger species(not roach),one is best and often a no.1 or more,one tip that must be done if tangles are to be avoided,is to cast(overhead) with as smooth and gentle action as possible.One thing ive omitted is plumbing the depth,as mentioned shot your float to the level you require(i would say 0.75in approx,unless extreme distance is required),then put your tell tale(shot nearest the hook),on at the loop for your hooklength,then put one of the say aa shot from your bulk with the tell tale,whilst plumbing i put my bulk about 14in away from the loop,tie your stop knot where you guess the depth is and cast out around the swim(remembering to leave your bail arm open to allow the line to pass through the adaptor),if the float cocks to its setting,its not deep enough,if it lays flat its way over and if it sits say 1-1.5in out its about right.Im sorry if this sounds complicated,but in all truth,once you've done it once or twice its easy peasy,good luck.
