ROCI motors lines

Hi. I was planning on attempting my Level 1 cert in May. I was wondering what, if any vendors typically show up and what lines they (or other fliers) typically use. Do people use CTI/ANW, or is it all Aerotech?

Also, Apogee used to say you could order a single H/I motor without a cert, but I couldn't find that text on their site anymore. I'm not sure how to buy an H that isn't too crazy for the flight, whether it's disposable or not. 

I've use Aerotech's variable grain 29mm casing with G's before on overbuilt Cheetah and Arreaux, but CTI seems to have good offerings too.

Lee Berry of Merlin Missiles usually attends our launches when not conflicting with WSR's and is an AT vendor. He's also extremely helpful and brings kits and supplies along with lots of motors. You could message him about this and he would probably hold a motor or two for you.
