Mmm. The Trebuchet has too many variants. My keyboard seems to have been damaged while moving to my new place, it has trouble capitalizing letters (with left shift). Go figure. So, not keen on writing too long articles.
Personal preference would be the Hellspawn or Chimera but... well, too much writing, again.
A 'Mech i've been considering is the Kheper but not sure about that.
I'll take a look at the Pathfinder, seems simple enough, despite not being a big fan of retrotech.
