Why all the reactors?

Well, my reactor works very well for me, I rarely have to touch it once it's dialed in (which is pretty easy). I think one of the issues with reactors is making sure it's big enough. Mine is really large, and maybe for this reason I don't have issues with it.
And as Tony said, balling didn't exist when I built my reactor, and since I have it, and it works, might as well keep using it.
