Many carbons have supplemental weights that can be mounted on the back of the inserts. Or, inserts are available in different weights (brass, aluminum, steel, etc.).
I was going to suggest you use carbons for your Judos, even before you mentioned that you normally use them anyway. Carbons are much tougher than wood or aluminum shafts, and will usually outlast them 3 or 4 to 1. Judos rarely get lost, so in my opinion, the extra expense of carbon is worth it.
I normally carry two stumping arrows: one with a Judo and one with a rubber (plastic) blunt. I use the Judo on soft targets and the rubber blunt on harder targets. They both last longer that way.
