Congrats!
I wish I could have been there... I still think the Umbrella would've been a cool cert rocket. (I'm the kid with the Saturn 1B by the way. Next launch I'll be flying a 38mm OD rocket too... significantly higher... on an E15W. Ahh, the fun of oddrocs.)
What motor? An I200W again? (Is that even the motor I'm thinking of?)
I wanted to cert on the umbrella, but the very nature of being a LPR oddroc upscaled into a HPR without some modifications just made it tricky. Namely the lack of TTW really hurt during the landing and so did the individual panels vs a single hexagonal sheet. I promise I will do a proper 38mm upscale of it at some point.
The motor was an I200W. It came down to me having the 6 grain case and feeling lukewarm about the H268R (I've been pretty lukewarm about redline in general, but I do understand larger redlines look stupidly cool and pics don't do it justice).
Also I do launches at the college every now and then(I've eaten a good chunk of my G64 arsenal...). If you are ever interested in launching together you should PM me, I even can pick you up since I have a car on campus, just double check with your parents and the usual disclaimers.
Will you be at the October launch?
