i've never heard of that one...i know abu makes a few orange ambassadeurs, a couple are in the trophy series(they have a kind of fish on the side of the reel, like a salmon, musky etc), and a 6000b, which is more of a budget ambassadeur(it has bushings instead of bearings)

the only reel i've seen with the "rocket" designation is the 6500CS, which looks like a mid 70's ambassadeur(it has the flat sides with 2 brake knobs), i'd like to get my hands on one when i get some cash, it'd be a great king reel
