The mold shoots flawless, its the perfect magnum grub style tail. I would really appreciate it even more if the mold had a modification made to the section that connects the grub tail to the flat square stub that comes off the sprue. I would prefer it to have a round stubby shape so that it can be welded with round bodied baits.
keep the same flat sprue then change to a 1/4" tapered round stubby off shoot connect blended into the grub tail. absolutely don't touch the tail shape or design its perfect.
Then a person would have the option to cut the tail off the off shoot for making grubs or cut the off shoot away from the sprue for welding tails to round shaped baits. that's a WIN WIN for makers.
Otherwise bad ass mold.
