Play with every one of my cues- whether they cost me a few hundred or several thousand. Never bring my higher end cues into a bar or a smoke filled room. Most who play with higher end cues from their collection leave one shaft unchalked or try both shafts and quickly decide on one shaft and leave the other as a claimed unchalked shaft.
One of my MAIN interests and enjoyments in cue collection is actually experiencing the playability of various cue makers - so you can't experience that without play- however, if you are meticulous, you can keep a cue looking relatively new for its entire lifetime. I am not concerned with cue price appreciation, a true collector is not a dealer in a profit sense- they are entirely different objectives; but can go hand in hand for some. My collecting is more about appreciation of the cue makers and their cues, passion for the game, and all the residual personal benefits that hobbies/collections/interests can bring to your life.
