@Koolmo: Actually the infocard for synth says it's a pill that gives people a similar reaction as the original plant because no plants or seeds were taken on the sleeperships.
@Korrd: No-one uses HF's becuase their armour is too low to take on the imported VHFs even with a mk 8 armour upgrade. The imported ships are alot more agile and can mount higher class weapons then the HF's.
A typical HF has class 6 - 8 mounts, which means the highest damage you can do is with plasma weapons, but plasma is so slow it's easy to dodge. Were as the imported and original VHFs can mount, and easily support, guns that can vaporise a HF in a one or two salvoes.
