The new one is far far far stronger, so don't go crazy - id recommend having 2, 1 for the car and 1 spare, but you are very unlikely to snap the new one.
Infact, please can everyone reading this take note. Id like to know who is the first person to manage to break one on the track, and pictures of the carnage (including what it hit, as thats likely to be broken too
).
