In my opinion, if the back end kicks out, you are not taking the fastest line. Very few exceptions exist to this.

You can play games with gas and brake in a FWD car to get the ass end to kick out and this is fine. It's a matter of weighttransfer from back wheels to the front so the front tires bite more and the rears loose traction. Managing weight transfer and momentum is what real driving is about. Pulling the e-brake unless you are doing an e-brake 180, is a cheap way to drift, and doesn't take skill, it takes luck.
I say do it right, or don't do it at all.
