It's going to be really tough to beat sucrose and potassium nitrate and still be able to call it sugar propellant. Anything you add will reduce the ISP not increase it. Richard Nakka's site is the best source on the internet for sugar propellant. SugarPro mailing list is the other. Rick Maschek will probably chime in once he see the posting on Arocket. IMO sugar propellant is good for some purposes certainly not the best choice to reach space much cheaper to use APCP. Even if your making the rocket and propellant. SS2S is a special case of using that type of propellant to reach space and not what would be considered a cheap, easy, or especially effective means of propulsion. It is wonderful for what it is useful for.
