Very well stated Inquiring Mind.
I started shooting archery back in 1951. (Six years old... Yep I'm a Geezer)
While technical improvements enhance the target hit probability, the romance of a straight bow or recurve holds sway over my choice.
Cross bows, Compound Bows, Arrows shot out of a rifle using blank cartridges, (Yes I have one), Magnum rifles with Telescope sights... Where is the romance of just pulling a string and shooting an arrow?
My 300 Weatherby Magnum shoots much flatter than my 65# Bear Takedown, but I just can't visualize Robin Hood with either a rifle or compound arrow flinger.
Compound bows are too complicated for me to maintain compared to a standard bow.
In a long term survival situation like Inquiring Mind spoke of, I too would choose reliability over the long term above slightly better efficiency.
I also believe that Olympic and field archery enhance each other.
However, shooting a field course is like a golf course for archers.
I get better exercise and enjoy it more than just shooting at one target at the same range.
Please don't take that as a put down of Olympic Archery. It takes more skill to be that accurate at 70 yards than killing a bale of straw at 20 yards.
I wouldn't give up one for the other.
Like I said, they compliment each other.
Back in the 1970s, the Cedar River Bowmen, (one of the archery clubs in the Seattle area) had several members who worked for a large taxidermy company there.
They arranged to buy several of the Styrofoam bodies that the company used to cover with skins of trophy animals.
These they covered with different fabrics and painted up like real animals.
Horns and antlers were made of fiberglass.
Thus the Bonanza animal shoot was started.
Targets ranged from Beaver at 15 yards to a 13 foot tall polar bear on the 80 yard walk up.
It was like shooting in Disney Land.
I shot in several of these shoots and managed a first place in Barebow, Bow Hunter class.

Here is one of the original targets... Looks real enough to try to pet.
Of course there were several side shoots.
They had a running dear target on a wire that they whipped un and down to simulate the bounding of a running buck. (Lost several arrows on that one)
My favorite was that galloping horse target.
They mounted a saddle on an oil drum and suspended it on ropes.
You got 3 shots at a slowly moving target while the ropes were being pulled to simulate a running horse...

(Lost a couple of arrows there too)
Another shoot my friends and I used to do was to modify plastic Frisbees (or make our own out of cardboard) and shoot them with Flu-Flu arrows.
We had six targets and would rotate throwing them for the other archers (usually three of four), so you got to shoot more than be just the trap boy.
There are lots of ways to enjoy field archery.
Best to you,
Steve
