It depends. How important are diamonds? Option #1 if diamonds are important, new island and new mine. If diamonds are not so important, I would go with option #2 castle upgrade. When you see the price for castle upgrades on the new island you will wonder how you can ever afford. The answer, getting more income on the islands you already have, usually that is best accomplished with getting as many three or four bed (depends on how often you play and your musical preference) monsters as you can. I feel you get more bang for the buck upgrading castles on existing islands. Remember, there is a law of diminishing returns when you start feeding 3 or 4 bed monsters above level ten or bringing one or two bed monsters to too high a level. I tend to keep my 1 and 2 bed monsters at level four (exception are limiteds which I always bring up to level 15). Three and four bed monsters level 10-12. I will bring certain 3 and 4 bed monsters to level 15 only if I know I will keep them. In the past too often I wasted money bringing monsters to level 15 just to end up selling them off to make room for the limiteds. Now, I am referring to the strategy I use on my secondary account based on the lessons learned from my primary account.
