^They're both playing with the previous models of the Tour100. The ozone tour ( 16x18 ) for Ferrer and Davydenko with the ozone pro tour (18x20 version).
I know Ferrer's is fairly light (330sh) and extended ( ~28in) with a hefty swing weight.
Davydenko also plays with a light stick (considerably lighter than Ferrer's) but more HH. Not sure if it's extended.
I was going to purchase some pro stock versions of the ozone tour a while back and remember that they were available in 55ra, 60ra and 65ra. They're lay-ups could be similar but don't know.
