pure physical Slayer Cyclone

Hello doing a pure physical Slayer Cyclone bulid and was wondering
if someone could tell me the different betwwen concentred effect support gem
vs increased area effect support gem? I have a 6 linked kondo so was wondering,
which one I should use for my bulid thanks.

increased Aoe = More aoe, no bonus damage. this is for clearing map trash/weak bosses
concentrated effect = less aoe, MORE damage. this is for hard bosses

if you dont want to gem swap, dont use either. Cyclone, melee phys, brutality, maim, damage on full life, fortify.

Thanks
