I think my low-power list based loosely on INN is still on CT somewhere. Just search by user and you'll find my cubes, I have the same name over there as here. Having Wilds does favor slow decks, but turn 2 Aggro is a very real thing that wins games as long as you don't give control crazy tools to go along with their favorable mana. In the stupid power cube I made using Wilds, aggro was almost completely replaced by combo, but in the INN cube Aggro is a pretty successful deck type.
Aw man, I loved this cube when I gave it a couple of spins. It did get me to think a lot about land bases and budget cubes. I found your thread here, if people are still keen to check it out.
I vividly remember building a sick Worm Harvest deck from that cube, and lo and behold, it was still there. Check out this sweet little beauty:

So the real question to you Mad Prophet is:
Does this configuation of fixing appease to your interests?
All of these lands are capable of going in any deck and you will only really pick them up when you need them.
Would you prefer a mix of Terramorphic Expanse and Evolving wilds, and if so, what split? I would personally do a 10:30 split myself..
