Getting back out in the garage today and going to pour up some older molds I haven't in awhile.
Just like everything since I was a little boy I've tweaked, twisted and/or modded anything and everything to make it better. I've modded many of both lead and plastic molds. Sometimes I've screwed up but I've learned and adapted with each one. Your bat jig I did like 4 years ago. Now a days I would've used a drill press on the hook eye part.
A simple solution to braid slipping would be just paint the eye and then run wire through it or just paint up to the eye to close it. I will still have to do this on the hooks I have with gaps.
Nothing special about this style head. I like the shape and look of it. Just another tool in my bag to catch crappie. Jigheads I prefer are weedless round head, pill head, hatchet head and egg head.
If you are making the switch from non braid I suggest this. Best I have found and I've used them all. I believe when I spool it my handle is on the left side and I put the label side of the spool towards the ground. It is some smooth line and doesn't get the crazy line twist like mono. I normally use 8lb for my casting but they sent me this 6lb by mistake once so they sent me out the correct and this was free.
