hi,i,m thinking seriously about going to waterfed,just a couple of queries you could help me with..is there any particular reason why a lot of wfpers do bottoms trad in my area or is it coz they don,t want to fork out for a 2 man set up..i do a lot of council flats,but a lot are just tops, bit worried about water dripping on to bottom windows am i better off doing them trad,and finally does lead on the windows have any affect on the pure water......cheers kev
