Sorry Andrew, can't help you there as not actually fished Laughterton or Clifton, I generally stick to Winthorpe on the Newark Pisc book (I live in Winthorpe so it's dead handy for the Mrs to drop off whatever I've forgotten to take with me!!)
Walked Clifton a couple of times and it looks promising and as you say much quieter than further upstream so won't have been as pressured. Downside is the pegs do not appear to be maintained so it's a case of hacking your way through
I'll probably get a Scunthorpe membership shortly and that will give options from Besthorpe through to Laughterton so will have to broaden my horizons!
