I understand that going to the prefered name drop company that the Registrar has will increase your chances of getting the domain name.
For future reference, I find that tech/customer support will often answer questions such as - "Who handles your deleted/dropped/expired domain auctions? - since the answer is one they should know and it's likely that the company would share in drop/auction profits = so they should be happy to tell you who auctions their domain drops.
People are often more willing or programmed to answer questions that are money makers for themselves or their company. IF they're not making money on the domain drops - or they're keeping them all for themselves - then it's more likely no one will reply. ;)
