I prefer 3 ounce inline bolts Chris, I have heard the theory of fish using the lead to throw the hook, stick a hook in your mouth and try to spit it out, see you when you get back from the hospital. Running leads , they tell me it acts as a pivot, what if it comes back towards you, dropback , and drags the lead with it, result no indication, with a heavy bolt at least the fish is hooked, but never say never, I do use running rigs and am prepared to ring the changes when not catching, but only at short range. In deep water at long range, the amount of stretch and water masking of strike equals hook pulls and drop offs, I use braid mainlines to counteract the stretch factor, semi fixed only where a snag requires a drop off facility, the swivel effect requires to much line movement to register a bite. Little experiment for those inclined, go to your local football pitch, cast as far as you can , get your mate to hold the lead and strike hard, the business end will not move or if it does would never set a hook.
