Hmmmm... I believe picking a cue is like picking a woman, so each person is going to have their own idea of what is a perfect cue is or even what a good cue is.
Let's take a woman, for example, and see how picking the right one, relates to a cue.
Now, does she feel good in your hands when you hold her with a gentle grip? Does she feel real good when you take some long strokes? How about the short strokes? Does your shaft feel good in the bridge, is it tight or loose? When you make contact, how does she sound? Do you like the sound she makes when you make contact? When you grip the butt, do you like the feel of it?
After asking yourself some of these questions, do you feel this is one that does "it" for you and you could see yourself holding onto it for a long time? If so, then it's probably a good fit for you.
Excuse me.. I must go now, HTH, I'm feeling a little flush
