I would put Dazing spell in there someone.
If you are using a two handed weapon furious focus is nice also.
Greetings, fellow travellers.
I's check Oterisk's Guide to the DD which is also discussed here on the Paizo forums.
I really like copper (for when there's not enough room for flying) or black. Consider taking Noxious Bite as feat if going for acid based dragon and if allowed.
For weapon I'd go with longspear. Gives you reach and you don't have to burn another feat for proficiency. Start fighting enlarged and brace it for the occasion you're charged at. Drop it and bare your fangs/claws for a nasty surprise.
I'd also consider taking sorc until lvl 6 for 3rd level spells right away. In addition your BAB progression will not be hindered even more.

Hey, glad you liked my guide. And thanks for the plug RuyanVe. I appreciate it.
If noxious bite is out of your way and you want to do blasting, I would recommend switching your dragon type. Acid doesn't have a whole lot of good damaging spells. Depending on how you read it, some people don't let the draconic arcana to work for just plain acid damage, but only for spells with the acid discriptor. It is kinda dumb, but I would double check with your GM before you stick with some choices that you can't undo. Of course, I can't really argue if you do spell perfection with Acid Arrow and fire off a quickened one of those every round. Also, if you have the time and your GM is the type, I would think that a Acid Arrow, Mass would be a fine spell to research.
If elemental spell does work for you, then fire snake is a good spell to do spell perfection with. If he decides to be nitpicky on it, then you can always try some words of power, and that should fix the whole acid description problem.
Blue isn't a bad plan either, for a burrow speed, and spells with the electric descriptor are much more plentiful. I've also been a fan of cold recently, and polar ray and cone of cold are pretty awesome.
No problem, Oterisk. I certainly do like your guide (although I will never be able to profit from all the goodness, since we've limited ourselves to CRB and APG)!
Anyways. I totally forgot about the bonus you get to elemental damage.
Hm. In this case I'd actually go for a dragon with fire or cold. Depending on how much you plan to melee, casting a fire/cold shield adds nicely to your damage output (bar immunities and resists) against big brutes (it may be a suboptimal spell, but the looks are certainly cool, pardon the pun).
And there's a fire spell on every level to take (and later swop out), with cold not far behind.
Ruyan.
Considering how many monster have resistance 10 (or higher) or are immune to fire, I would try to make it fit in your build (and there are numerous monsters with the same defensive abilities for cold/acid/electricity...).
Metagame advice:
Maybe you could talk to your GM (or have done so already) and get information what kind of campaign you're gonna be playing to know what are the monsters encountered most in endgame.
I do that for the ranger(s) in my games to let them pick favored enemies and I know, similar advice can be glimpsed from the player guides for the official AP.
Ruyan.
Ah, sorry. In my previous post I assumed, that you hadn't decided whether to take it or not, thus my remark that you needed to fit it in your build, i. e. replace another feat with it or shift feats around to take it earlier. I didn't see that you'd planned on taking the feat at Sorc3 already - so you've already fitted it into your build. All's well.
Ruyan.
@RuyanVe - Just core and APG? That's kind of rough, but still doable. At least you still can get Robes of Arcane Heritage... and...
Well, if you don't get elemental spell, be sure to get a rod or two of it if you can. That way you free up a feat and you can be ready for those contingencies. Also remember that changing the type of damage doesn't change the descriptor. Works really nice that way.
Dragon's Breath is also a great spell.
If your GM allows it, sure. I thought that since it was from the ARG it would be out of the list of your approved sources.
It would turn you into a more versatile character. It also wouldn't change your build much, you could just take your Skill Focus at first level instead of 9th or so.
Sorry, no metamagic rods at the gaming tables either, Oterisk.
But I can't complain. It's still a lot of fun and the others are at the same power level.
Ruyan.
@ astura- I don't have the ARG, so I can't really give you advice on the particulars. I would say at this point, either would be fine. Just go with your gut or with your preference.
@ RuyanVe- Well, there is something to be said for simplifying things. At least they let you play with prestige classes at all. And you still get the Robes. It could be worse! You could just do core. My group is doing that for Rise of the Runelords.
