Sorry about the delay man, I've got a lot of things on my plate these days, what with work, uni, work, tennis and the inevitable amount of time us waste thinking about women. anyhow, I dont have the specs for all of these players, but of the list you have, this is what I could come up with.
If you can get specs of Tom Martinez, they'd probably be a lot more accurate, since JCS have their own proprietary machinery which is apparently far more accurate than the Babolat RDC that i was using.
All the specs I'm about to quote are for strung (i think) frames with the grips "as is". By that I mean, how the players would actually play with it.
PS, when I quote the racquet type, I'm just going to quote what paintjob it is. Often times I'm not really sure whats under the paintjob because quite frankly, I have a life, and dont know every racquet that every manufacturer has spat out in the last 10 years.
Daniella Hantuchova - Yonex RD-Ti 80 (i think it really is one though)
string: VS Team 130 (25/24kg)
balance: approx 324~325mm
weight: 358g (strung)
Elena Dementieva - MP Tour 1 98 (i think it was one too)
string: Alu Power (22/21kg)
weight: 345g (strung)
