Dragonite Moveset?
So I have a 97% iv lvl 20 489 cp Dratini I have 92 candies and two other that I can transfer if needed. So recently I got 2 10k eggs and if they both hatch Dratini I can evolve so I figured why not ask what movesets do you think I should power up(I am personally hoping for DT/HU)but what other movesets do you think would be good to power up.[I am lvl 29, Dratini never spawns where I live so reroll is not an option the ivs are 14hp/15at/15de]

Yeah, I'd go into it with zero expectations other than fulfilling a Pokedex entry.
I made that mistake recently with a Tyranitar. Only seen two Larvitar, one hatched, one wild. The hatched was a 97% one, which I walked for 465KM, and the anticipation was high almost the entire way. What did I get? Iron Tail/Fire Blast. :/ I was pissed. Still haven't decided what to do about him.
You can power up any moveset that has 2 STAB moves.
But what puts a huge smile on my face is that you are asking the question without a dragonite, and without knowing what moveset you will get. Its the equivalent of spending your first expected paycheck when you just got the call to attend the first round interview for a job.
