Junior 7-F got even smaller. This should contest with the LCT-1E. It's probably a better idea to just run the common XL280 and increase the armor on your shield arm & head, but this is FASTER.
Since you are already extremely cool and nobody expects a Light or standard engine on a light, this build coul actually work too.
What's the purpose of this in scouting? Without ECM smoke diving is risky, you lack range and going in on brawly mediums with this doesn't seem like a good idea. Is this mostly for running down Clan smoke divers? I didn't think pure smoke dive was playable for clans.
