Hi Edward,

Thanks for your input on this.  I read the paper proposing mfix awhile back 
(persumably this is Erkoek and Launchbury's one -- can't locate it right now).

I'm not sure I follow this other commonly proposal replacement your mention 
above though, and googling "mfix alternative" etc isn't turning anything up.

Would you happen to have a reference/example.

Thanks!  Tyson
