g2x-brace carbon/aluminium ?

[mini-mad]

hello everyone!!!!!
i want to build a g-maxx and i'm waiting for the new products:018:
but i have a question :
for you;whose the best ? g2x-brace carbon or aluminium ?
it's for a race utilisation ;not bash or trial:007:
i think carbon is better(lighter) but is it strong ?
