let me explain,54 yrs old ,wc donkeys years and because of this constantly in pain,just usual neck ,shoulders,back etc we all get it.Now, after reading jeff and other lads posts about convertingpoles from one use to another i decided to give it a go.First let me say this,i am not into diy i always believed you can t make any thing as good as you can buy it,and also it s not about saving money.Anyway converted sky blue pole to waterfed and also just bought a 4 quid adapter to change unger pole to waterfed.WOW why have i been in pain allthese years,now don t get me wrong i m still not pain free after work but it s a million times better than it was and i actually look forward to work again.The ease with which i can reach awkward windows etc and not having to release clamps all the time,this i found was worse thing for me, has been a godsend.So if you are old and decrepid try this yourself. cheers mick
