need new rotors for our magnum??

i need new rotors for the magnum.i was thinking maybe i should go slotted, drilled and slotted or dimpled and slotted to try to keep the damn things a little cooler stopping this freaking tank. what do ya think? is it worth it? or just a waste of time?

heard of the drilled ones cracking on the street so i was actually looking at the slotted and dimpled ones here

any thoughts??
