So or Mo - Which mirror type is better?

Hi Guys,
I’m changing out the laser head and mirrors that came with my machine for Cloudeay ‘E’ Series units.
I’m putting in an ‘In Beam’ red spot at the same time.
I was wondering if anyone has any thoughts on the relative merits of Mo mirrors over the more normal Si type?
Any insights would be most welcome.

I dont have a preference but I have never read anything that indicates one mirror is better than another.

Mo mirrors are 'forever mirrors'. They can be polished over and over and brought back like new.

I did read somewhere that Si mirrors can crack with lasers 100w and above, more so if they aren’t kept clean - Is this a real world problem?
I inadvertently ordered a set of each from Cloudray, and the Mo set are noticeably heavier than the Si, so I suppose I can try both and see if there are any real benefits in terms of use.
I was leaning towards the Mo type due to the ability to re-polish them, but hey, I’m new to this in terms of low power CO2 equipment, the ones we have at work cut thick steel plate.
We are currently commissioning a new fibre machine too, so exiting times ahead.
Thanks for the advice too, it is most appreciated.
