Use what you must.

This is the route i've been using so far. Now I'm not quite sure going around "A switch out of reach" is faster than getting in with the jammer, but i think i tested it and going OOB turned out to be slightly faster.

Never mind, Solais just told me it was not the correct version i was testing. But the Armory solution is a fine workaround.
