Who are you fighting with now also? Your second front?

You may have to deal with the getai sooner or later anyway. The amber route provinces can be good money makers for you too, especially if kallatis is included with its seaport. But if you haven't taken rhodes and crete yet, and if you can hold off a bit longer - I'd try to get them first, and then you can start making money from them (and they are pretty safely protected from attack). Then you can fight the getai. Also - I always use archers to take out the unshielded drapanai before I get anywhere near them.
