Where the c/o adjusts the springload is how the shock manufacture decided to do it, the SAW c/o's for the Titan also adjust at the bottom of the shock.
With stock upper and lower control arms you really didn't pick up any more travel, but as you now know you have a much higher quality travel and that can count more then pure quanity of travel...
The DR's mount "upside down", for some manufactures this is to reduce unsprung weight, for other's the shocks can be installed either way...A standard twin-tube emulsion(many white shocks...) shock needs to be mounted body side down for the valving to work correctly.
