I've been trying both Modeller-derived distance restraints combined with 
dihedral and h-bond restraints from Permol ( 
http://www.biologie.uni-regensburg.de/Biophysik/Kalbitzer/permol/permol.html 
) and all Permol-derived restraints. For a single template, Modeller seems 
to be better.

Yes, deleting hydrogens would be my preference and this works fine. Thanks.
