This is likely the most OP way I've found to get lots of wood and raw rubber fairly early in any mod pack with Minefactory Reloaded. Here I'm playing FTB: Unleashed 1.1.3 (Minecraft 1.5.2) & I'll cover what you'll need to put away tree taps from IC2 rubber trees for good. You can easily put your own spin on this if you wanted to use it instead for wood for charcoal and apples for juice as examples.
