Years ago, I received two new shafts that were built generally to the same specs, but one was a half ounce heavier. I asked if the shaft was weighted and it was, immediately inside the joint insert closer to the ferrule. The cuemaker drilled out the weight and nearly matched the weight of the other shaft. I don't know if Tad adds weight to his shafts, but it might be worth investigating.
The other option was already mentioned, which is to buy a lighter shaft. I agree with other previous advice to avoid substantially changing the cue.
