I don't know, for two more tonnes you get an c-UAC/20, that's it double the damage for "just" 20% more weight, though is 3 times the heat.
Having said this, a lot of people has "complained" about the c-UAC10, that is in an uncomfortable tier.
With the speed increase it is slightly desireable over the C-UAC5, if you can fit it. However the insane heat nerfs to clan weapons really hinder them.
