Legendary Buddy Dilema

I just hatched a Bagon (+64 candy) that made it possible for me to finish maxing out my Salamence a few weeks ahead of schedule.

This leaves me wondering, who should I walk next?
-Larvitar: curently sitting on 102 candies but I already have 3 maxed out ttars + 2 lvl 30s so I don't think I really need more of that
-Dratini: 702 candies (enough said)
-Bedlum: 362 candies (likely enough to evolve a Metagross and max it out once i find a good candidate, and don't plan on powering up more than 1)

So I'm pretty much done with pseudo-legendaries until gen 4
I don't fell I have any urgent needs, and other buddy candidates could be Chansey (I'm not to keen on powering up more defenders though, mostly because of dust) or Togepi (in preparation for gen4).

On the other side, I'm pretty rare candy starved and have a Groudon, Mewtoo, Kyogre, Rayray, Ho-Oh and soon a Latios on the candy waiting line.
Being in said position and with the halved buddy distance I'm finding the Legendary Buddy idea more and more appealing, at least during this event. What do you guys think, should I walk Lengenday mons? if not, what am I missing?
Thanks for the feedback!
