Balance?

I hear that if I have the duel antenna mod (the one where two cat5 antennas are twisting around each other) it gives the car a bad weight balance because the antennas are way too high. Thus if you turn you'll tilt over... is that true? if i turn really fast i tip over anyways (3.8 motor). =P I'm thinking about the duel antenna mod but if its gonna ruin my driving abilities then i might just reconsider it... I'm removing the crippler, and adding a hard antenna on my remote so thats already gonna be like 30-40 some feet of reception... but i still i want MORE so i was thinking about the antenna thing. anyways tell me your output. has anyone tried it out there? what do u think about the range? wut about the weight? is there anything else i can do? thanks!
