So I was playing around with list building and wanting to use 2 units of speeder bikes. After filling out my core, I saw that I could drop in my AT-ST, but that would leave me with the min. Troopers. So:

Vader - Saber throw

Stormtroopers - DLT x3

Speeders x2

AT-ST - Grenade launcher

So it hits 799. The obvious choice would be to drop a unit of bikes for more troops, but I kind of like it. Thoughts?

Vader needs force reflexes as well, You can't do speeder bike and an AT-ST in a list and expect it to do well with objectives. Pick one and fill out the rest with troopers.

I would rather see two AT-STs than one and bikes personally. Yes bikes are fast and neat and what have you but AT-STs are practically untouchable.

I have quite success with a similar list:

Vader (Saber Throw, Reflex)

4x Stormtrooper

2x Bikes

AT ST (Blaster-Cannon)

The main goal of the Stormtroopers is to apply supression tokens and survive, not doing dmg, so no need for DLTs.
If you hide them in the first few rounds of the game there shouldn't be problems with accomplishing the mission, even if it needs troopers to be fulfilled.
