Summary so far:
Arms:
open to damage near overpass
tend to be slower
tend to be tippy
more of an entanglement risk with other robots
ball alignment during pickup can be too critical and slow
can play a "deny the ball" strategy by herding opponents track ball
harder to block before act of hurtling
can block from behind overpass
can easily place the ball on the overpass
can easily remove trackball from overpass
can be in possession of track ball at end of hybrid
Shooters:
can score faster and on the run
usually faster on the track due to lower CG
seem to be fewer shooters than arms
tend to be less tippy
greater track ball pick up range and speed
many not good at herding for defensive purposes [opponents ball]
can not possess track ball immediately after hybrid period
many less effective at removing trackball from overpass
less effective at placing track ball on overpass
but again then, who says an arm can't shoot!!!
