I have been using the AC/10 Vedette in Alpha Strike and have found it good for the PV (probably not for the Cbills).
Been playing it against a Capellan player, and he uses Po's rather often, which is very similar (slower but more armor).
However, the Vedettes, especially in the FWL 6-tank formation, really can do their work. They can hit above their capabilities with Special Ammo (armor piercing to the head is just the tank version of Boot to the Head), and they get 1 higher TMM than the Po as well as being a Skirmisher and therefore able to be in a cavalry formation. They're zippy, punchy, and frustrating - well armored enough that not even an Atlas hit can put it in Forced Withdrawal, but no so punchy or well armored to earn the attention of anything more...
...I don't want to look at the Cbills cost with the surplus Fusion engine though.
Makes a great pairing with another FWL tank experiment, the Soarece - in our campaign, the little Vedettes can use their fusion engines and some water to refuel the Soareces in operational moves, while some of their guns share ammo types (both have AC/10s) and their fast speed and annoying propensity for stinging pairs well with the utter inability of the Soarece to die, barring fantastic luck.
Motive crits are a problem, and are a showstopper for the Soarece, but it isn't trivial to shut them down totally, and their armor means you can plonk them in a place and it is Defended™.
