I really like the lines on this rocket, the one fin forward, one fin back.
One thing really great about these asymmetric fin rockets, the fall with the fins UP, meaning when rocket meets terra firma (sometimes terra asphalta or granita) very unlikely to break a fin.
These rockets are stable, in that the flight path itself is straight, even if they sometimes (no always) do some corkscrewing. Since I am not going for altitude, I like to think that adds to the cool factor.

Had a nice corkscrew AFTER propellant burnout during the coast/delay/smoke phase. Hope to go up from A8-3 to B6-4 this weekend.

Very interesting design. More unsymmetric than anything I've seen in the flesh.
