Aloha and welcome aboard!
10 years is a very conservative timeline in my point of view. Doesn't put you in a rush. Wing keels have a disadvantage of burying themselves you you go aground in mud or sand. Like an anchor
. They are not as efficient as straight fin keels. Long keels track better downwind and when beating to weather
There are books
published about the advantages and disadvantages of each keel design.
In your case I'd find as many boats as you can to look at, go aboard, discuss their seakindliness with the owners and then decide.
I'm familiar with Bruce Roberts
designs but not Origami.
I know this isn't what you want to hear but buying
vs building is a way better deal in today's boat buying
market. You will be spending as much or more by building (usually much more) and you'll be putting off sailing for 10 years.
I don't know if you currently sail but I always recommend a basic sailing course and at least joining a club for a year for a bit of on the water
Good luck in your choice.
