I've been thinking up some ideas for a high performance rocket that is BT-60 sized. Where I'm stuck is trying to determine what readily available nose cone is the best choice. I have some PNC-60NA(Patriot) and PNC60AH(MeanMachine) in my possession. I'd rather stay with plastic if possible. I think a PNC-60RL would work nicely, but are they available anywhere? What cone do you guys/girls think would be best?
