Which one needs more testing?

My cousin is going to buy a beyblade, and he is asking me to give him advice.

And his choices are Storm CapricorneM145Q or Flame Libra T125ES

So it doesn't really matter which one he gets

But I wanted to ask the forum, which Track or bottom or w.e needs testing to be done, because He is willing to test for you guys..
This could have gone in Beyblade General.....

Post another topic when results are posted. Of the two Capricorne is the one that needs to be tested.
