It seems like a lot of production cues put phenolic tips on break cues. I use my old playing cue as my break cue and, though I have used several friends' break cues on occassion, I don't have a clue if I've ever tried a phenolic tip before. Now, as I am beginning to consider buying a dedicated break cue, I'm wondering what the difference is, in terms of playability, between phenolic tips and layered leather tips (like Samsara).
