When is a fade not a fade?

Put more simply, when do I start calling my fade a slice?  Is there a rule of thumb that if you didn't mean it it's a slice and if you did it's a fade, or is it to do with severity?  Is it a case of something like going sideways more than 10% of the distance forward makes it a slice?  I'm just curious as to the difference. 

I'm assuming the rule will be the same for hook and draw. 

Mine I and was on my woods and was apparently caused by shafts that were too soft.  I had modified my swing to compenstate for this.  I now have new woods with stiffer shafts but am growing into them.  I'm a little scatter gun with them at the moment, varying from slice, through fade, touching straight, moving to pull then onto draw.  Unfortunately, I never know which is coming next!!!

You think it will be that quick?

I thought a fade was a controlled left to right shot, where a slice isn't. Some golfers, can make a ball fade 60 yards.

Correct, Danny, a fade is controlled, whereas a slice is out of control.

Don't worry about the 'power fade' you may have, Breadsall has got quite a few right hand dog-legs that are ideal for that type of shot.

I need a course that watches my ball and adjusts itself to ensure I land on the fairway.  If my fade was consistent then I would adjust for it.  Problem is, as soon as I adjust left the fade doesn't come and I end up intrees on the other side!!!. 

So, according to John, I have a slice, not a fade.  I think I preferred not knowing!

I done that after a heavy night out.  Played well until the hang over started kicking in cos the headache was stopping me concentrating.  I think it forced me to slow everything down a little, relax and not try so hard. 

I think that I hit it straight and the course cheats and moves!!!
