the fastest truck i have is the xtm excellerator and the nemesis and the lst2 are very comparible out of the box . even with the 3 speed in the nemesis its not that much faster( which i also have installed). so it realy comes down to price, the lst2 at a main you can get for 570, and the nemesis for 560. persolally i have fun with the nemesis but i would buy the lst2 again.i also have the genesis and i think after i finish installing the mtm brake system it will be retired with the rest of the trucks untill i can break the lst2.
