All of the recent talk about C300 stuff cracking easily brings me to post this topic here since they have the same people make Track's coverstock.
I have not had a Track ball crack at all on me. I have drilled many Track balls, and the only one to crack was a Phenom that I drilled. It cracked around the fingers after about 20 games (it was a customer's). Track quickly replaced it. That is my only experience with Track equipment cracking.
If C300s stuff cracks easily you would think that Track would as well. I do not see that at all. NOW----I have drilled several Track balls for myself (Mutant, Threat, Phenom, Phenom Unleashed, Darkside, Crunch) and none of them cracked at all. I make sure to bevel (or sand) around the finger and thumb holes enough to ensure it not cracking. I do not use Grips, and have not had a ball crack. I have not had a ball from any company crack-----except Ebonite, thus the reason I do not use them anymore.
What are your experiences with Track equipment cracking? IF you have had them crack around the finger holes I do not want to hear about if the driller did not round the edge of the hole off. If the edge is not rounded off, it is destined to crack, I do not care who makes the ball.
