I would go with the speeline towers, I am running the Dynamites but they are practiacally the same and I don't think king kong could break them and you save a little upper weight.
As far as the losi breaking, it doesn't break any more or any less then any other car on the market. Just ask him how much he likes handling his saddle packs, or did all the hudy setup stuff come with the car? Not hating on the xray at all, just hating on the individual that would try to put you down.
