overall i would say not bad , good choice of studded pads (am looking for more for my ultra vet squad)

you realise this guy has initiative one .

If he uses the power fist, yes, he will have initiative one. But he also has a power sword, which he usually uses. He has the power fist to tackle tanks and high toughness models.

Acording to DA' rules , the powerfist drops your initiative to one ,eaven if you dont use it .
Straping on a melta bomb woudent slow you down but not so hot vs walkers.

a powerfist is good if you want to go after big nasties and hope your WP keeps you out of harms way , aka maneus calgar (emperor bless him)

Actually, the rule refer to strikes with a power fist and not the characters initiative in general. That means I can use my power sword with my regular initiative to fight basic troops, such as space marines and Tau. I've been using the old Powerfist and power sword combination on my independent characters for a long time now, I wouldn't be using the power fists if they dropped my initiative down to one regardless of what I attack with, I would be just better of using two lightning claws and it would cost less points too.

this is interesting academicly in the way two difrent groop entrepete the same set of rules , i understand fully yout pov but the way we play it here , the int 1 powerfist is apselute , you have a powerfist on you , your int is one, ofcourse you do have the +1 att for an extra CC, note a powerfist/lightning claw combo would track , str 8 rending
