even if you use a float stop the lead will never be able to eject with a running rig you need to use a clip on lead because if you have a float stop shot putty and so on the lead will still be on the line as the stop is kepping it on there that is why lead clips are the best you could have as many shot as you like the lead will still eject when under pressure really i only use a rinning rig when stalking the fish and realy that is what the rig is for to present a bait in the fishes mouth with minamle resistance while stalking the fish in the shallows .also when you put a shot under pressure it will slide of the line take it you havent been float fishing ay?
At the start of your statement you say that if you have a float stop, shot or rig putty on that the lead won't come off the line. Then at the end you say that under pressure, the shot will come off?
Which are you saying is correct?
Im not even gonna start on running rigs or your opinion on lead clips, but would like to suggest you experiment a little further before making such sweeping statements.
