What I really think they have improved on is the core/cover combos of their strong pieces. The earlier strong balls like the Freak, Mutant, Super Freak were just too much cover and I wasn't able to get much use out of them. They had a tendency to really burn. But the lower end stuff was sometimes not enough.
The Phenom changed all of that. That's the first big piece that I could throw on a wide variety of conditions. It didn't burn, it recovered and lasted a long time. Then came the Rule, Xception, Aggressive, X5.0 in addition to all of their great midline pieces.
I agree with EX, they all fit nicely into a lineup and Track has a variety of covers/cores (Power Plus, WOW2, PEAK, Fang) to find a reaction.
