HELP! ARMS for Mechanica

I main Mechanica and Ninjara, but mainly Ninjara. I'm happy with my set for him right now (Slapamanders, Triblast, and Sparkys), but I can't say the same for Mechanica. I've used the Revolver since the beginning and like it, and I change between the Kablammer and Whammer, and I like those too. Its just the 3rd option I don't know about (although tips for my other choices help too!) I've tried Nades, Megatons, Toasters and Homies so far. They're ok, they just didn't click with me the way the first two did. Should I give any of those another try or should I try something else? Any help is appreciated!
