The only type of Sans that I would consider bottom watering are birdnest types that are sensitive to water in the growing points. They seem to be so sensitive to water being where it should not, I water them carefully.

Most of my Sans are in big pots so it would be impractical to try bottom watering. They would have to sit in so much water to make the soil damp. I just water carefully from the top until it just starts showing in the pan underneath.

Some soils it seems that you cannot get damp from just contact with water. If you pour a small amount through, it seems to start a wick action and dampen up all of the soil in contact with the water, not just where you poured it though.

Is there a particular reason that you are avoiding top watering?

Well I just repotted them in Frank's cactus and succulent mix and the soil looks so dry even after I watered it, so I was thinking that maybe if I could just fill the dish below and let it decide how much water it wants it might be better than possibly overwatering it. I do this with a lot of other types of plants and they drink it up pretty quick. Thanks for the info though.

They are succulents, need not watering frequently. Once soaking or bottom water once, it may stand for serveral weeks without water if the weather is not real hot and without direct sun.
It will rot if it's cold and water logged, especially water trap between leaves.
