Fosters in Birmingham keep all spare sections in stock. Speak to Ade - he will put you right.
I dont tend to fish much in the winter although I have got a match kit with No4

laccy in it somewhere. My kits have either red, black or white hydro although I've heard the purple is good so I might get that next. Also thinking of getting some pull bungs so I can fish lighter laccys and tighten up for the big boys.
