Heel toe double strokes double bass?

[Slider]

Is it possible to get really strong heel toe double strokes for playing double bass to where it actually sounds really good (where all the notes sound even)? I have heard a lot of people do heel toe double bass to where it does not sound all that good at all. It does not sound defined at all and it sounds sloppy.

I want to know if it is truly possible to do really great sounding heel toe doubles for double bass to where all the notes sound real defined and powerful?
