Get the 77D I just bought it and love it I use it with the Tamron 16 - 300 great combo if you don't get the kit.
I always carry my stuff on board I carry on 1 body 7 lens it all depends on the size of your bag to fit in the overhead bin.
No problems with the Mark 2 I bought it as soon as it came into the store never had a problem with the focusing it's a good choice so is the 77 and 80D also 70D.
>I Matt is mostly portrait I would prefer glossy for landscape pictures.
If I'may not driving this is the lens
I carry with me 1 lens does all.
You want a nice tripod get the Grottoes MH5310 it fits perfectly in a carry on suitcase I use that when I fly when I drive I take my Bogen
Why don't you take the D7200 and buy a Tamron 16-300mm that way you could only have one camera and lens and you won't have to look at all the glare trying to take a picture. And a cell phone is not good for action shots.
