I agree with many of the AZ members regarding a break cue for her.
1. Get a super pro water buffalo tip! Its Hard but you still get control!
2. Get the weight to mirror the weight of her playing cue! Consistency, Consistency, Consistency!!!
3. Get a sneaky pete/full splice break cue. They are better balanced and better weight distribution. "IMO" Stick with an Ebony,Purpleheart,Cocobolo full splice with maple forearm, they have the "WEIGHT" you need in a proper break cue! The other woods are "WAY" too light. "IMO"
4. Get a wood to wood joint with joint collars! Any good cue maker will advise the joint collars because the pins have "POPPED" thru the wood way to often when the joint area is not reinforced by phenolic rings!
5. Contact Schmelke to make her one on the cheap and it will last for ever and they will make it the same weight as her playing cue, the same ferrulle size, The same shaft taper.
6. You do not want a whole lot of deflection on your break cue. So, get her the 3/4 inch ferrulle on it to decrease deflection. 1 inch ferrulles work fine if your used to them but if you ever break with a Meucci and their 1 1/4 inch ferrulles and you will get that whip appeal that no one loves especially me when I want and need control!!!!
7. get white ferrulle material the black stuff works but consistency with her playing cue which has white ferrulles is much better by making her maintain the same sight profile she has with her playing cue!!!
Just my thoughts on the topic but I am Half Crazy!!!! LOL
