I fond this mod and I think that it is very cool on how it adds new weapons, tools and amazing features. This mod also adds a few new creatures. http://www.minecraftforum.net/topic/1659892-151tinkers-construct/
This seems to be an advanced enchantment mod that adds mobs and liquids. After a quick skim of the post I see the following problems: 1. ComputerCraft and Tinkers Construct together has some odd problem. It's being investigated, but the cause is unclear. 2. Adds Mobs, SKCraft is notorious for disabling mobs, so this seems pointless. 3. Adds world gen. I'm not sure what is included in the world gen, but it may require a mining world reset.
The bad thing about tinkers construct, is that it's only the 1.5.1 version that has the liquids(and mobs?). Otherwise, the 1.4.7 version only has the 'infi'nite tools. But it adds no enchantments whatsoever in the 1.4.7 version either and the tools and weapons added, aren't even enchantable. When it comes to the it adding world gen, the only world gen that it adds iirc, is ores that spawn in the nether, which is decently easy to find if a person is willing to go out far enough into the nether (which most are not).
