may I make a suggestion?
I personally rarely use cylinders. I rather make this rectangular spline (interpolation set to adaptive) and lathe it. Then I reuse the shape over and over for cylindrical objects. It gives you that ability to instead of having a mathematically perfect cylinder, you can bow the side out a little.
visually it really helps. And you can do alot of shape changing really easily by adding a edit spline modifier to the spline before you lathe.
Also there is a handy trickk to make the center align up, but you can probably do that.
