I try to find the best possible mana base for my GWU Flicker deck.

I've come up with the following possible lands, which I could include, but I only need like 36-38.

Can you help me evaluate them? For example, it's hard for me to decide if a Mirage Fetchland, which makes 3 colors (with the duals) is better than a Painland, which makes only 2 colors, but enters untapped.
Or if the old filterlands are better/worse than the new ones.
Or how many utility lands should I include?
How many basics should I run?

3 Duals
3 Fetchlands
3 Shocklands
3 M10/Innistrad Duals (Sunpetal Grove)
3 Scars of Mirrodin Duals (Seachrome Coast)
2 Painlands (Adarkar Wastes)
2 Filterlands (Skycloud Expanse)
2 Mirage Fetchlands (Grasslands)
3 Ravnica Karoos (Azorius Chancery)
3 Shadowmoor/Eventide Filterlands (Flooded Grove)
3 Zendikar Refugiums (Graypelt Refuge)
3 Lorwyn Vivid Lands (Vivid Meadow)
2 Guildgates/Invasion lands
1 Evolving Wilds
1 Terramorphic Expanse
1 Seaside Citadel
1 Exotic Orchard
1 Reflecting Pool
1 Krosan Verge

Utility lands like:

Tectonic Edge
Wasteland
Strip Mine
Alchemist's Refuge
Moorland Haunt
Stirring Wildwood
