@Nfrance -- With the obvious caveat that this whole conversation should probably be moved to FTB support to let the real experts get eyes on your problem, you might want to try tweaking your java settings (within the FTB or MultiMC launcher wherever is appropriate) -- I can't speak to the MultiMC launcher as I don't use it. But in the FTB launcher, try the following:
Go to Options tab.
Near the bottom it should show Java version: 1.7.0_60 (if that's your java version) and a large "Advanced Options" button. Click the button.
On the Advanced Options screen, there is a smallish box for Additional Java Parameters, Try each of the following lines for two successive runs and see if you get better or worse performance for any of these settings:
This one is for a lower-memory situation:
This one is close to what you already have, but slightly bumped up:
It may not work in either case, one may work, or someone smarter than me may step in and say "Holy Cow! Don't do that, do this instead!"
In any event, good luck!
