of the class for antenna and propagation expertise, strongly urged me  
to go to ~100 feet for a single-tower station, and to put the 40M 
beam  on top.  I did it, and have been glad I did.

    I totally agree. I'd do a little bit more  homework and run the HFTA to 
see what the arrival/takeoff angles will be.  

But aside from that, 100' gives you a sweet spot  on 20M and lower 
arrival/takeoff angles on 40. A small tribander at 40-50' on  a side-mount will also 
be invaluable.
