3x Termis: MoK, 3x Fists, IoW.
I'd probably swap one fist for a power axe, here, just to have a sacrificial wound to throw out first. Plus, well, that's almost a lightning claw on a zerker champ or something.
Termi armour, Hammer of Blind Justice (AoBF proxy, stolen Blood Angels relic), Power Fist, MoK, melta bombs. 190
With the AoBF and meltabombs, you have enough of a threat spectrum to take out nearly everything without having to fall back on that fist, basically ever. Ok, Wraithknights would provide a bit of a problem, and if you want to give a T6 MC the chance to AP2 Smash your termis to strike last and wound at 2+... that's your choice, but the fact remains: against the vast majority of stuff in the game, S6 (7 on the assault) AP2 I5 is going to wreck a helluvalotta face, and meltabombs will take care of vehicles. Plus, you know, chainfists.
If you're really committed to the modeling or something, I'd drop the meltabombs and keep the fist--but honestly, I find the AoBF and a bolt pistol complement each other well. Not only are you avoiding a specialist weapons for yet one more axe attack, you're also
allowing yourself to batter ineffectually with your pistol if you assault a squishy unit you don't want to wipe, but want to lock in combat through the enemy shooting phase... (wait, Termi. Damn. Would have to buy a plasma pistol for such ineffectual battering, which... meh)
I expect you probably realize I'm going to praise the merits of bikes over raptors, so I'll accept your decision here and move on.
I'd try to get Rhinos for those Zerkers... but I dunno where the points are coming from, unless you drop half your Raptors, which frankly strikes me as unlikely. Though you could drop the power fist and a chainfist and be a good ways toward a first, there...
