Apropos of nothing, I was reading FM: Lyran Alliance last night and noticed a blurb in the infantry section that, at least immediately post-secession, the LAAF was side lining battle armor, so having a fast omni to deliver them really wasn't a priority. Coupled with a general shift away from Omnis (see the Argus and Thanatos), the Stiletto was probably doomed to never see an omni version.
