Mechs on the other hand, I have a problem with, so I selected three mechs as standards to measure compatibility. So as long as they fit within the range I will use them.
Standards - Atlas III (100tons), Centurion Omni (50tons), Koshi (25tons)
There are also some that I am uncertain about, because they just seem off to me. The two light mechs on the right just seem way to small to me.
Locust (20tons), Koshi (25tons), Phoenix Hawk L (35tons), Mjolnir (25tons)
