I'm not really understanding why you need the heavy weight up on the nose of the A-Rig.  Most of the ones being sold are made out of a polyester resin and have very little weight on the nose at all.  I'm going to make a harness like you see in the link below and then take and cut the head off of a swim bait and push it through the harness.  I also thought about pushing it up through a white gitzit or tube type bait.

I also really like the look of these swimbaits.  Great colors!
