I like em on the hellspawn ... in fact the spawn has a new lease of life in general with the new stuff.

I am tempted to take the biggest MRMs on my spawn though and no ammo ... i don't expect to live very long once i got in i want it to hurt for them to kill me though

I used to use a Kodiak with 2 SMRM40s, 2 SSRM6, cLBX20, ERPPC. Nasty.

Also on a Kodiak: 10 SMRM10s.

Can you say "chainfire"?

Hellspawn
MRM40+2
3 ML

Owens
2 MRM20+1

Raven
MRM20+1
4 SL

Strider
2 MRM20+1
1 CFlamer

and finally, a untested one

Owens
2 MRM10
2 CSTRX4
2 ML

I like the CSMRMs now. The 6 second recycle isn't too terribly bad, given that I use CLBX20s a lot.
