Since the original question concerned a move from 50 to 100 feet, in my 
experience a single 10 Meter antenna at 100 feet is almost always too 
high to do much good.  

With a single (multi-band) antenna, I prefer the 60 to 70 foot height for 
general operation.  It is still "too high" many times on 10 Meters (ca. 
2 wavelengths) but it "about right" (1.25 to 1.5 wavelength) on 15 Meters 
and a bit "low" (.8 to 1 wavelength) on 20.  Only if one were to have a 
stack of antennas (ca. 30/60/90 feet) would 100 feet be an appropriate 
"top height" for 10 meters.
