You can still get choked after a failed hip throw while standing. I call it the spider monkey because some a-hole jumps on your back and makes your life hell. The point is if you screw up the hip throw, it's open season because you've given someone your back, which is probably the most dominant position in grappling. You might as well put a "please submit me" sign on your back, because anyone who knows what they're doing will capitalize on your screw up. Like DB said, there's safer takedowns. The DLT is so common because its relatively low risk, and pretty easy to pull off.
