Not a cheap solution since i'm using a rail set and clamps, but something like this can be done using other techniques. It doesn't take many of these large washers to add up to about 8lbs. and the further you can position the weight, the less you'll need to counter the weight in the front. Much easier than carrying around workout weights, making this portable Jib truly portable. I guess something like this can be used in the rear of your Shoulder rig too, if you can live with the aesthetics.
