If the tip holds chalk well, and can get maximum spin on the ball (close to the miscue limit), and doesn't damage the CB, and you don't mind the added hit efficiency (energy transfer), and you don't mind the sound and feel of the hit, it could be a good choice. It will certainly last a long time and won't need to be maintained or changed often (if at all). I like the idea.
PS: Stay tuned for my follow-up video, which I hope to post soon. My BK Rush cue with a phenolic-like BK Hybrid tip performs just as well as the soft and medium hardness tips I tested.
