There are others as well such as the A5's, low impulse booster motors for the second stage of three stage rockets such as 1/2A6-0 and A8-0, and 13mm B motors.

I feel these would sell well since no one else makes them currently. Then when people see the quality of the Semroc motors (i.e. good tracking smoke, accurate delays and ejection charges that are just right) they'll then be eager to buy common size motors from Semroc.

18mm shorties would be nice to have, but profit-wise would not be as big of a seller as those listed above. Those would be something to add down the road after the Semroc motor line is established in the hobby.
