CF will always break some sooner than others. Alum can break too but it usually bends before it will break. So the few grams that you save with CF is it worth it? All depends on your driving. I am notthe best driver nor the worst but even the Boeing grade CF shock tower broke earlier this year at the nitro pit. The crash wasn't even that hard but it broke. CF looks way cool but personally it's not for me. I'll take a kHz tower over an alum tower any day.
