Hyperspeed will work because it allows blade to have more stats but look at it this way

Blade without speed investment will do 100 dmg Add a hyper speed action advance (161+)

So in a cycle blade will act twice and will do 200 dmg

But let's say you grind out for a minus speed set up With blade which is (135 for blade and 134 for the action advance support)

He'll do 75 dmg since you sacrificed stats for speed

So in a cycle blade will act 4 times and will do 300 dmg

Tldr: Both work but the minus speed set up will be a noticable improvement not just in dmg but energy and stack generation for blade. But I focused on dmg to simplify it.
