Two harp problem

So here is my current deal, I’m kind of focusing my kit for a specific project.

I am leaving in February to Thru hike the Appalachian Trail for about six months.

So obviously carrying my washboard and a brace is out, and I want to really only carry two harps.

I’ve been working on playing bones one handed while playing harp with the other hand, and making some inroads.

So I’m looking at two harps with the broadest coverage for people I play with.

I’m starting the trail with a mandolin player I currently play with, who mostly plays in G, F, D and Dm.

So, currently I’m leaning to my Lucky 13 in G and a Low F powerbender.

With that combo I feel solid in G, D, F and C just in first and second on each, and moderately confident in Am, Em, Gm and Dm in third and fourth.

The lucky 13 in G is probably my favorite harp, and bends really well. I feel like I can play in A or E on that harp just by working it a bit. Not as ideal as having an A, E or D harp with me, but doable.

Feel like this covers me on pretty much most keys I’ll run into.

Of course my mandolin friend could decide to play in Bb, or something, but I could just leave a turd in his tent in that eventuality.

Thoughts?
