You can achieve lower average fail times by minimizing your chances for the sun/moon fails. Since both the cave and the island have equal chances of breeding the spring dragon (~10%, per the sandbox), and the island has a higher chance of breeding sun/moons, it is best to focus on your island. The same idea applies to level 10 and 15 dragons: using level 10 dragons will result in fewer sun/moons, over time. So, the best outcome (lowest average fail times) results from breeding level 10 dragons in the breeding cave, but never level 15 dragons in either the cave or the island.

tldr; breed level 10 dragons in cave for fastest spring dragon
