1) The Hei$t -- this will allow you to do exactly what you want.
2) Are you looking for true skid-snap, or something that is just more angular than the Hei$t? If it's the first, then the first ball that comes to mind is a Visionary SS Ogre. If you just want more length and a more angular backend reaction, try an AMF Night Hawk Pearl with a weaker drilling (5 x 4) or a Storm T-Road pearl (maybe a little stronger, 4.5 x 4).
