CG: Adding Ballast to Tail

[lrobichaux]

Does anyone have experience in adding ballast to the tail of an EX/FX-3 to shift the CG back with as little weight as possible? Majority of my flying is solo and I've been maintaining a favorable CG by adding quite a bit of weight on the rear cargo area. Looking to achieve the same result with less weight. Tailwheel is Acme Stinger + baby bush wheel. Would prefer an option where it's not terribly difficult to remove the tail ballast as needed for the specific mission. TIA! (pic for attention).
