i have never used a break away rig. guess i figure that terminal tackle is expendable.
i pour my own sinkers and have found that no rolls work well. i also hahe a bank mold and plan to get an egg mold. they all have thier place. the flat for current, the egg for placing a bait and waiting 5 min and popping it up and let it roll to the next rock and so on.
thats probably the only 3 styles ill mold. they pretty well cover my needs.
me nad a buddie have discussed getting a jig mold togather but thats a different deal.
the no rolls work well for current and regular lake fishing. i use them alot. even on a carolina rig drifting. i have fornd they dony snag as much cause of there low profile. they will snag though. and they do take a little more time to mold with the pull pins. my mold does 1 ,1-1/2, 2, 3oz sinkers. the banks pour really fast cause ya pop and drop and are ready to pour again.
for someone wanting to get a mold your doing the right thing. research.
i figure ill get 4-5 molds and a pot and never buy another sinker. i have a big tub now of banks and several containers full of no rolls. i can pass the art and molds to my son. i fig the only sinkers ill buy now is split shot. they are small and require good soft lead to bend.
i use tire weights. for a non moving sinker they can be cleaned and work quite well. just spent 6 hrs yesterday cleaning out about a hundred and fifty pounds or more of them i got from a buddie that bought a wheel balancing maching. i got me 76 little ingots made up about 1 1/2#each.
there are several fellas on here that make thier own sinkers. don't be afraid to ask Q's.
