Guardians, Mirrors, and Spirals all have some pretty neat options, so maybe do some window shopping to compare them and see if there are any you particularly like? On the cheaper end of the spectrum, I particularly like Blue Mineral and Spiraling Supernova for Spirals, Octoflyer for Guardians, and Internal Energies and Cooling Embers for Mirrors.
Basically it boils down to how you want to take care of the issue of having a dragon whose looks you're not too fond of. Putting genes on it is expensive and do you like the outcome enough to justify buying all the genes? Scattering is a big gamble since all 3 colors are re-rolled, but it can pay off big time if you get new colors you like, especially if you didn't like the first combo at all. Changing the breed/putting on a skin is sort of like a cheap bandaid fix, but it's relatively inexpensive and you can choose what the dragon ends up looking like.
I ended up going the "put a skin on because genes are expensive and don't look as good as I want them to" route with both my progens. xD; Sometimes I feel like I should gene them up to do their status as progens justice, but well... I kind of got used to them looking like they do:

That combo looks a whole lot better than I imagined, especially before I scryed Stained on there. o: Stained to the rescue!
