In some situations, "squeezing" all the light from around a ball may cause your bore to be too small, but I haven't seen that personally yet.
Best thing I'd recommend is close to this.
Load the ball in the bore (ie; freak insert, TechT back, barrel back, etc) The ball should be able to almost sit on top without sliding through. Put the bore to your mouth and blow the ball through. If it goes through smoothly (without rolling itself out) then you have the right bore size, if you have to take multiple breaths to blow it out, then its to tight.
