So I am running a few units of marines (champions with PF and some special weapons guys in each) in rhinos. I have some extra points and was thinking of adding combi-weapons to the unit. I was wondering would it be better to put the combi-weapon on the rhino or on the champ. I know that if you put it on the rhino it has a chance of getting destroyed but would it still be worth the risk?

No because Rhinos are easily stunned or shaken which will stop the combi-weapon from being used (not to mention it isn't that hard to blow a Rhino sky high). Put the combi on the Champ.
