I have a rule that I live by, I regret nothing I have ever done or not done. It's very simply, we make decisions with information we have at the time. We can wish it didn't go the way it did, but there is no way we can make ourselves "responsible" for the decision to sell that IBM stock when it was 25 cents a share, we didn't know things would change so much. I can't beat myself up for selling my house in 1986 for $115K that would be "worth" $700K just 15 years later, I made the decision with the information I had at the time.
I am not saying you are beating yourself up, I know you aren't, I am just talking in general.
At the time that Falcon WAS a better choice for most of us.
