So many reasons why a Flemish is better both in looks and use. Especially around the loops where endless loops can be more easily damaged then a padded Flemish twist. Plus it took me a few hours to learn to build a Flemish string.
For quiver, it depends on if you want a bow, back, side, etc kind. I prefer safari tuff Arrowmaster because it protects my arrows and keeps my fletching dry. And makes creeping through the woods easier. Pricey but I was given one at a 3D tournament.
