The Brooks is a tall bag designed to go high and keep a load close for the best COG possible. I have done a fair amount of testing of load placement, and heavy weight above your ears can make you tippy. So high and close is good, but don't put too heavy of weight too high. On the Revolution, the load shelf is movable, so choose your location.
Gatekeepers are light and highly adaptable. As long as you shut the gate, you should be fine, however they are so light it isn't a big deal to carry a spare or two. I carry a couple extra straps because they are very useful (clipping things, even moving a stake location on a tent if need be). Yes, we also use them to attach nests to tents, to raise the canopy similar to line locs etc. , hang a luci light or whatever.
