welcome.
Lots of info here. Read it all and choose what you want to use for yourself.
Longbows are fun, and yes, it takes some work. Don't penalize yourself though. If you want to hunt, but can only shoot 5 yards accurately, then go, but only take 5 yard shots till you can stretch to 10 yards etc.
If you can, try making a few "stump" arrows using a judo, hex head or any similar blunt, then go walk in the woods. Pick out targets and watch them arrows fly. No animals are accidentally injured this way and you can shoot as many times as you wish, as far as you wish, and as difficult as you wish. Its never dull that way.
Here's some free advice. Don't get too wrapped up in the tuning game until you are shooting well enough. Sure, your arrows have to fly well, but you can make lots of arrows fly well without totally fine tuning and getting carried away in that whole premise. Have fun first.
