Guild Wars 2

So, I need to upgrade to an ascended back item from what I have now. I kind of like something like this: http://wiki.guildwars2.com/wiki/Endless_Quiver

Two things:

1. I was looking for some suggestions on cool looking back items I could make.

2. I have bauble bubbles left from the SAB and I might as well spend them on items that I can use to create a back item. Would it be better to buy Obsidian Shards, Crystals or Philosopher Stone’s to make an item? I have no intentions of ever making a legendary.

Thanks

A note on the quiver — there is currently one in the gem shop, as a skin. It has a notably different appearance from the Ascended one, though. However, if you simply want a quiver and have a wider range of statted items that appeal to you, you can get that skin and apply it to the statted item of your choice.
