Keep in mind everyone that the machines we're currently using are not meant to be the be-all-end-all for us- we'll have the chance to obtain considerably better equipment and gear later on, so don't be afraid to leave some space on your machines instead of min-maxing everything. [@Athinar], you haven't addressed that first bullet I mentioned- in that both the powerful boosters and external power cores are both mounted on the back, so there is a conflict.
