chain stay length important
Make sure the chain stay length will accommodate your panniers and your feet. The LHT has 460mm chain stays 20mm longer than the Tricross. If you are 6'2" I am assuming you have pretty long feet. Heel strike is always an issue. Long chain stays part of the solution!
Pushing panniers way back on a rack to get them clear of your heel can make the load sway a bit more than usual.
