I initially prefered the IJC curves interface also.

Actually, QTR allows for better control.  I now use the QTR point 
list, which allows up to 51 points on a curve.  Moreover, decimal 
points are allowed in the boxes.  I believe the full 16 bit range is 
available (as opposed to IJC's 256 steps and only 10 points).  This 
degree of precision is way beyond what even the most compulsive would 
need.

It does take some experience to learn how to do the work using the 
points list.  It has a curve preview that is very useful, but beware 
that the smoothing algorithm is not previewed.  As such, you have to 
look carefully at the final curves set that is displayed when you 
make the profile.  That will show whether the smoothing algorithm has 
done something unexpected.

At any rate, both of these programs are excellent, having different 
strenghts.  But don't worry about the ultimate degree of control in 
QTR.  At least with the Windows interface I use, there is almost 
unlimited control.
