I use a double #4 latex for fishing matches where there are lots of silvers and small (up to 3lb ish) Carp. I find it works well, especially fishing to hand with the silvers. I guess a double #6 would work ok for larger Carp. Definately worth trying [^]
I recently went to doubled up preston slip, and can truly say i wasnt happy with it at all, its great on the strike but as soon as a metre or so comes out it begins to bottom out quickly making the pole bend, i didnt like its action and have now gone back to Vespe hollow now im happy again. Its one of those things in it if you dont try it youll never know, It may suit some but not others.
My top kits are fitted the same i.e.from the bung make a loop and stretch holding bung against the outside of the kit the loop is then adjusted so it doesnt jam in the top section tie a knot and re-elasticate the kit you now have a soft single on the hook-up and the loop comes into play on the run,my match results and pleasure sessions tell me its working well.[:T][:T]
Petert the big loop comes off the bung,you must make sure the double loop doesnt jam in your top kit at full stretch or it wont work I use preston slip from 6 to 14 in this mode.the line Iuse is Ultima with 6 Preston 3.2lb main line 2.6lb hook length for small carp to 6lb and tench to 6lb.PM me if you need more info[:T]
I use preston slip no4, 5 6 and 8 doubled with a pulla bung. I fished a local lake this morning and caught big crucians, skimmers and tench to 4lb and found double 5 perfect in conjunction with a pulla bung.
