You can put Xbows really anywhere on that list, but you will generally want to drop trophies and do both at once, because let me tell you from experience, being down just one Xbow and trying to stay in Crystal 2 kinda sucks.
Also, Xbows are kind of amped up Archer towers. Personally, I wanted to wait to upgrade them (and thereby incur more expensive elixer reloads) until I was a bit less elixer starved (like ~9 mil for camps, ~5-6 mil on DE barracks that I've neglected, 6 mil for loons, 6 mil for giants, 6 mil for archers, 4.5 mil for healers, 9 mil for PEKKA (didn't do in TH8)). Now I'm coming up on needing much less elixer, so I'm starting to also think about getting xbows up.
