I like the FaN simply because it fires faster. (Sure the reload sucks but what the hey)

Bonk only when I need to get past exactly ONE sentry. Multiple sentries not so much.

Sandman=useless. 95 HP is like one hit kill from most classes.

i agree with the FaN and Bonk (even though u can use it to speed up over maps using their sentries to project urself - takes pratice)

though i like the Sandman just because i can dodge most stuff that one hit kill you so yh

also makes me think twice about my health though

i found out that lowering you mouse sensitivity will increase accuracy in aiming, since you run fast you mouse doesn't need to be fast.
