Have you even tried the BD chalk??
Yes, but that's not the point. The point I'm trying to make is that if Tweeten was developing a chalk that was substantially different than Master, I seriously doubt they'd be so coy about the differences between it and their other lines.
I emailed Skip Nemecek a while back about this. Here's the contents of my email and his response.
My Email to Tweeten:
"There have been quite a few rumors swirling about Blue Diamond Chalk, including one that has Tweeten as the manufacturer of the chalk. I was wondering if you could dispel some of these rumors:
1. Is Blue Diamond made by Tweeten?
2. If so, does Tweeten use a different chalk blend than what they use in Master Chalk?"
And here's the response I received from Skip Nemecek (the President of Tweeten):
“To answer one of your questions, yes we manufacturer Blue Diamond Chalk for the Norditalia company in Italy. Sorry but I cannot answer the second question.”
Like I said before, if you think that it improves your game, you should use it. If the manufacturer refuses to say that there's anything different between the two lines though, I have my doubts that it is anything more than the placebo effect.
Personally, I'm such a hack that there isn't a product in the world that would help my game. Although I am working on becoming the #1 men's player in Guam...
