My thinking comes from American WW II pilots that flew bigger, less mobile fighters against smaller, faster, more mobile Japanese fighters.
(sound familiar?)
With a Biggs list:
Luke
R5-D8
WingMan
Biggs
R2-D2
Shield Upgrade
Wedge
R2 Astromech
PTL
The idea is to add a bit of survivability to ships that have good firepower, but not great maneuverability.
so Biggs is the target - he turns INTO the hook pilots and they do the jousting.
It was executed either by two fighter aircraft side-by-side or by two pairs of fighters flying together. When an enemy aircraft chose one fighter as his target (the "bait" fighter; his wingman being the "hook"), the two wingmen turned in towards each other. After crossing paths, and once their separation was great enough, they would then repeat the exercise, again turning in towards each other, bringing the enemy plane into the hook's sights. A correctly executed Thach Weave (assuming the bait was taken and followed) left little chance of escape to even the most maneuverable opponent.
Been playing around a bit - but would like better players than I (and there a LOT of you) to let me know if you think this is applicable to X-wing.
