Just to throw another option at you.....
Norco take their sizing & geometry very seriously... they claim to make each size frame grow or shrink to the appropiate body size with more detail than other brands.
If I was looking for a new bike right now the 29er Sight would be very high on my list for reasons I just mentioned (because I,m 6'3" with particularly long arms)
For you, I think the Optic 29er XL might be good? They offer "reach and stack plus" options too...(?)
....and because they are not direct-to-punter, you might be able to do test ride to see how it fits..?
