Thanks for a bunch of great insights.
I've tentatively decided what I'm going to do. I already have a 60# recurve to shoot. I'm going to start shooting it again regularly. That will give me the power I feel I don't have in the longbow. I'll also start squirrelling away some money for a future longbow purchase, around 60#. The 60# longbow should give me a balance of power and control, and the 30.5" draw should give me some 68-70# @ 28" actual power.
The added power may be like having a 4-wheel drive in San Diego, but it's always nice to have it when you need it.
