question about armor/insignia combos

whats the "best" insignia combo with armor (for pve)?
normally i use dreadnought's chest and leggings, since they get hit the most, and radiant head/gloves/boots since they dont get hit as much and the extra energy helps
when im using 13+ strength i use sentinel's chest and leggings and radiant head/gloves/boots for the same reason
just making sure this is the "best" combo and if its not, what suggestions people have

IMO Brawlers everywhere. 126AL vs. physical means you're only taking 1/8th of the original amount of damage, and 90AL vs. elemental still puts you at the top of the pack. Since you have enough armor with the brawlers sig, you can the defense to 1 skill and beat the crap out of things.

chance of hitting chest 3/8, energy from radiant in chest 3
total chance of hitting boots, gloves or head 3/8, energy from radiant in theese 3.

I.e It doesn't make any difference.

I just got a radiant set, survivor set and legionnaire's set and mingle between them as appropriate - the first 2 are for pvp, the last is for pve as I'm basically always in frenzy, flail or rush. But in pve I wear whichever set I feel like wearing wrt looks, not stats.

I currently use the survivor insigna (+hp). It allows me to use the +5 armour grip for my weapon without having my hp be too low.
