Joe... Both of those are great ideas. I thought about wrapping lead around the arms, and I should that. But the idea of inserting lead (perhaps a long lead sinker like those I used as a kid with a bait casting rod??) inside the spool is an excellent idea! It gets the lead "inside" the hand where it is easily... excuse the pun... handled. But it will still add weight when needed... when the bobbin is hanging.
