Over the years I have had to replace my ivory ferrules on my Motty several times due to cracking. I feel that ivory is an obsolete material for the performance end of a cue compared to modern materials. I'm going to replace them with something synthetic. What would you recommend for replacements that will play the same. I love the " aluminum bat sounding hit" I have now and wish to stay close to this. Is ivorien(sp?)a good replacement?
