I am not sure this will help much but I have a lovely XL Specialized Epic Evo from 2020 carbon full bouncer and I thought it fitted me well, no issues. Then I had to buy another bike (don’t ask I “had” to) and it was a Specialized Epic HT as I thought it would be identical but as a 2022/3 model the geometry is different and it fits me much much better. So much so the Epic FS will go soon. (and loads of this years Epic Evo and HT going cheap if you shop around in the traditional recommend what you have STW way).
The moral for me with this little anecdote was that in both cases I bought them with no test ride (simply couldn’t get one) but they are night and day different so next time around test ride no matter what for me as the best way to find that comfort for long XC type rides 🙂
All bikes I think are pretty damn good now so if you can ride and then pick you will be a much better place and air suspension is so easy to tweak and tune to suit your needs and style of riding.
Good luck hunting, trying, and buying the next bike 🙂
