Isolation Cones/Bearings placement on CD Transport

I would like to know what is the best configuration for placing isolation bearings underneath a CD transport? Should I place 2 devices towards the front of the component and 1 in the back or 1 device in the front and 2 in the back? Are there any audible sonic differences either way? I am going to use a set of Final Lab's DARUMA 3-II isolation bearings on my EAD T-1000 transport. Thanks for the help.
