there are loads, it follows the 32 bar (at least i think its 32) intro that all jump up tunes use so u can work out a double drop with anythin...i quite like it with spor aztec @ the second drop. but i normally jus use it as a tease as its a phat bassline from no where.
I've actually had a hard time finding some decent mixes with it. I've only found one so far that I'm really happy with and that's mixing out of Fired Up - Friciton & K Tee.
