I'd probably skip the past drivers. You can be spoonfed whom to call. Regardless of that, newbees certainly don't know what questions to ask, and, wouldn't be able to pick the fly crap from the pepper anyway. If the present drivers are playing the game right, making money, happy, then they have not dikked up yet. IF you are in that category (not dikk'in up) then go for it if the present drivers are ok with it.
