I prefer setting an appropriate pattern entry altitude for the simple reason that many places I fly have a ridge or other high obstacle to clear before I get home. The LX9000 software will show if my current final glide will clear the offending obstacle. Granted, it isn't full proof, but it gives a general idea. Setting the reserve to zero negates this feature.

I agree with Craig and John.

1) I don't like the idea of setting up a final glide where I get no indication if the calculation works out that I will clear a ridge by 1 foot. I'd like to know if it's going to be close.

2) Most contest finish cylinders are 1000' - the scoring equivalent of ground level (sort of).

Therefore 1000' reserve is what I use. If I have a half-decent climb I will go to at least Mc=4 plus an additional 500-1000'.
