As I understand it, If you want to use the whole "mass increases"
thing, you have to differientiate between inertial and gravitational
mass (even tho every thing we know of has equal amounts of each, and
prolly everything does). Otherwise, the explanation of just having the

momentum increase is good enough. it's all just how you look at it.
That whole mass increase thing always bothered me too, btw. But not
nearly as much as people who state that warp drive works by lessening
a ships mass. Gah! An infinite amount of 1/2 of something is still
just as infinite as a whole something. And let's not even get into if 
9.999... = 10. Remember that? :)
