> I have been a dedicated ivory ferrule user for almost 20 years on my Schon.
The rules are pretty simple.
First,if you wouldn't sleep there,don't leave your cues there. This primarily means hot or cold vehicles.
If you have no choice but to leave your cues in a place less than ideal (like in the car while eating,shopping,etc),try and let your cues acclimate to the surroundings.
What I do in these cases is wrap my hand around the ferrule for 60 seconds or so before hitting balls.
I personally hate the pads,so I have to make sure I don't let the tip get too thin. The only one I've ever cracked was because of this,and I DO break with mine,just not full-time.
Use fresh chalk so you don't let it get all scratched up and nasty. A wipe-off with a towel occasionally is easy maintenance. The surface is so hard chalk will just not stick to it,and no pores like the linen-based stuff means you don't get the little spots that won't come off. Just keep it wiped off.
Every now and then,rub a little yellow carnauba wax on it to keep it from drying out.
With proper care in regards to weather,I don't think you can hurt an ivory ferrule playing pool with it,unless you're jamming it into the cloth trying to masse or have Larry Nevel-like power.
I think they play better than anything else out there,they look nicer,and sound GREAT. Tommy D.
