Dave - just visited FW forum, couldn't be bothered to read all the 100 or so posts but I got the general idea.
Quick question - do we use safety rigs so that in the event of a break off we don't tether a fish, or is it so that we can get a fish out of weed without the lead snagging.
If the answer is the first part then surely it's not beyond the realms of possibility to fasten a run ring to the eye of the lead with a loop of line, then if the lead snags it will pull free from the clip and act as a free running rig, also if the line breaks it will pull free altogether.
If the answer is the second part then there is an interesting viewpoint on FW about fishing for carp in heavy weed.
BTW I saw Roto's comment about 'for hundreds read a few' but for the sake of argument I ignored it.
PS I wasn't having a pop at Roto or Wol for that matter, they just strike me as being the sort of characters that would have a tackle box that would cover every eventuallity.
