In this case the visual manouevering option was not needed as the flight was light enough to meet SID climb requirements OEI.
I don't agree with that statement.
The visual maneuvering option is required because if they lost an engine say....just as they crossed the golf course and began their visual climb to Tollgate, they need the visual maneuvering option to either;
A) maneuver visually in order to reach the required height at Tollgate and therefore be capable of going IMC and maintaining the SID gradient, or,
B)maneuver visually in the figure 8 to return to land.
