Ultra marathoners perspective on the 6x Pro / Solar

The Fenix series has a wide range of options to suit a wide range of activities and individuals.

For those ultra marathoners out there.  What your take on the 6x Pro and 6x Pro Solar?   We've all been out there (unless you are an elite, I suppose) with a portable USB battery to help juice up an Fenix to keep it running for a full 50 to 100.  Carrying a usb battery isnt the end of the world, especially since the Fenix charges pretty fast.

The thought of solar, even if its first incremental step is pretty cool.   However, with a softer crystal, coupled with the ever present possibility of a tumble into rocks or tree, it may be a gamble for a Solar version rather than a sapphire version. 

All recent Fenix has had troubles with firmware at launch.  Fenix 6 appears to follow suit.  I expect it will calm down in the next month.  So all the sensor drops, and everything else will get fix.  So I dont see that as prohibitive issue to jumping into a new Fenix.

So to you ultra runners -----  The question is.   

- Solar just gimmicky new tech,  keep the sapphire

- Solar gimmicky new tech, I want a part of it (possible with a screen protector)
