Are there any iterative design techniques,for FIR filters, other than
park's-mclellan and least squares.

Meteor uses linear programming:

The source code is available in Pascal or autconverted to
C with p2c.

There's always the windowed sync approach, i.e. take an ideal response and
window it to make it practical to implement.  This works with "classic" LP, HP,
etc. filters, but isn't readily applicable to other more complex filter
responses.

MAXFLATs are the most accurate in narrow bands, and very simple to design.
