Oops, sorry, I meant to put "Buy exotic shard, then upgrade Young Ahamkara's Spine with Xur, Sorry for the mix up

I personally think Young Ahamkara's Spine is one of the best looking exotics I've seen, so the moment I had the opportunity to upgrade them from Xur, I did. However, coins are relatively easy to come by, so exotic shards are inexpensive in my case because I have three characters. I noticed you only have two characters with one of them below level 20. This is perfectly fine, however, it makes strange coins more difficult/tedious to earn each week as you can only do the weekly heroic once a week to get a guaranteed 9 strange coins; where as someone with three characters can get 27 coins a week. In your case, is this an exotic you would wear for a long term or would you rather wait for something else/better? While I think the spine looks amazing, the perk it has is admittedly lackluster, but that doesn't stop me from wearing it.
