Sadly, my math seems to be rusting away, and I don't know If it was ever 
good enough to figure this. My intuition, though, makes me think that a 
planet with a highly eccentric orbit would be easier to detect (using 
stellar doppler ****ft) than one with a circular orbit of similar period. 
Am I full of crap?
