Welp, nope, they didn't work at all... this really bugs me... time to install fresh again, process of elimination time to find out just what the fek is going on and which mods are conflicting if it's even a mod.
EDIT:
Ok so after testing with just the basics here is what I came up with
You can look here for more pics with a better idea.
It only happens when you're in the air(had to use the jetpack to accomplish this which meant I did need to give myself a TMI install, but only to get the items into my inventory then swap the jar file to without it so that it's ONLY the 4 things required to play IC2.
At ground level looking at either MFSU or MFE the game runs fine, but soon as you look "down" at it, that's when shit hits the fan and the spikes begin. This is an absurdly stupid bug if you ask me, and for the life of me it makes no sense. So I don't know, looks like I'm stuck tinking with buildcraft mainly until this is fixed or someone figures out a fix. And yes, I deleted everything, just ran the mincraft.jar and had it download it all over again, one at a time, install each mod, open rar, dump files, close minecraft.jar, start minecraft, close minecraft rinse repeat until finally drop the IC2.jar into the mods folder, everything WORKS, it just doesn't work well for me(and the other i7 in the house with similar specs) apparently, and this pisses me off because I've been playing IC since launch... just took a break for months while alk was busy making IC2.
