I have all three of these pieces. All of them are great additions for anyone's arsenal.
For me, the Too Reckless is the straightest of the three, with the Reckless and Massive Damage about the same. With that said, the Massive will out hook the Reckless if there is more friction on the lane surface. It just plain reacts moreso to friction than the Reckless.
That, and the fact my Reckless is less angular than the Massive when compared actually gives a nice three ball combo in my bag. Depending on the center I bowl in, these the Reckless and Too Reckless are always in my bag, with the exception of dropping in the Nexus Pearl for the Massive Damage in one of the houses I bowl in.
All three balls are layed out the same. Can't remember the exact numbers right now.
Who needs a 300 or 800, when I have a 294 and a 295!?!?!
