I (almost) always start at an angle with my YV-666. Works absolute wonders, folks always have a hard time avoid getting caught by Bossk on the flanks, or they'll have to try to turn to face him and leave em' open to his escorts.
The actual angle differs, but the usual goal is to look for a diagonal path through the obstacles and make sure the YV-666 is line up to just cruise right through it (with some nice, tight spots I know I can safely turn through!).
