Another large trader here spoke highly of DB Autobahn. If you don't have the equilibrium for high tier (JPM, GS, DB, MS, etc), then you can start looking into second grade (FC Stone, MF Global, etc). I would begin with taking a look at the top (EBS by means of a high tier prime) and work down the chain from there.
