I'd like to formally request the addition of Modular Power Suits to FTB. This mod adds customisable power armour to the game on par with (or even superior to) the Gravitation Suit from the Gravitation Suite, assuming you outfit the suit with the most advanced modules available at once. It also includes a customisable multi-tool that outstrips pretty much any other tool in the game once appropriately modified.
The mod is under rapid development and already established compatibility for both Universal Electricity and IndustrialCraft2. It includes support for vanilla, UE, IC2 and GregTech-based recipes, which you can toggle on or off in the config file.
Using the mod personally it already has no block nor item conflicts whatsoever with anything in the existing packs and I use it without making any config changes: a literal drop in and go. Additionally the most recently version (build #89 as I write this) appears to have fixed all the outstanding compatibility problems with other mods, all of which were minor anyway.
I concur. This mod is awesome, and should definitely be in ftb
