I don't bother covering 0-0 either anymore. What I tend to do is Dutch it - which means covering all three results at three different bookies for an overall qualifying loss of about two quid, regardless of the final score. The reason for this is that you can take advantage of other offers at the same time. 888sport will give you a free bet if your result is screwed by a late goal, Boyle sports give you a free bet if either side hit the bar.
And after all that, I then have my 50 quid risk free bet in play to do what I want.
