Wish I Had $600
I have owned over 50 cues and my Diveney Sneaky Pete was one of my favorite hitting cues. Just the right amount of stiffness and very solid and playable. I've had Balabushkas and Black Boars that felt and played fantastic that I didn't like as much as my Diveney. It's that good.
This cue is going to make someone very happy.
Good Luck with your sale.
