Wow, three of the same post.
I remember someone from Track coming on here and saying that when the Rule and Bully came out, with Goo and M80, there was a natural reaction to say they were the same. But in essense, BASF came in with several new resin formulas, Track chose one they called Goo, Columbia chose one they called M80, but they aren't the same.
In a technology generation sense, they are of the same generation. Just like Superflex, Powerplus, PK18, and Accu-tread.
