Update:

I went to the REI Flagship store and they had the Osprey Argon 85 in stock in XL, with an XL hip belt. It's not a perfect fit (like a custom pack would be), but I didn't have the time or budget this summer to go that route.

I'm going to make the Osprey work for now, and if it's still not a great fit in a few summers, I might go for the custom pack.

Thanks for the feedback. I'll certainly try to post some reports from Romania. I leave in a few days...

Cheers.
