Tips for Winnu?

I'm playing a game this Saturday as the Winnu, it's my first time playing them. They're the last faction I have to play, and then I'll have played them all.

I'm having trouble deciding what starting tech I want.

Probably depends on the board arrangement, but I do know if I want to get to mecatol first I'll probably need to go blue.

Yellow start could help economically, and lends towards PDS style game play. But so does a red start.

Green start is possibly the worst start in the game unless I have like 4 tech skips.
