I doubt there are many people left with more than a bottle... but you could ask for a plus of something... also TS was bottled in Mid April, so I doubt it tastes as good as it used to.
Given the age and demand, I'd say 1+ for Huna '15 with the + being a couple fresh hoppy cans like SoS or Heady would be fair. Fresh it would've been closer to 1:1. TS is one of the few beers that was transcendental for me, I'd love to try it through out for several months down the road to see how it changes. Good luck.
