IMHO 50 ft is high for 10 and 15m. 40 ft spacing seems to work pretty well
for me too. I have not had an opportunity to work through all the variants.
HFTA is a very interesting program and well worth the time to learn it
especially if you are somewhere other than flat ground.
After modeling my situation here I will probably add another 4 ele Steppir
at 30 or 32 ft to compliment the one at 70 ft.

Steve,
HFTA and AO show rather good results with 40/80 or 50/90 foot stacking. The
40' spacing improves performance slightly on 20 meters and does not overly
impact 10 Meter performance - particularly if the 10 meter antenna uses most
of the boom length.
