Do you have Bushido? That's the big question as Lightning Strike gives a 50% HCI. Couple that with the HLD from Mace & Shield, and you're pretty much going to achieve Perfection most of the time. I actually have both properties on my archer. He uses the Mace & Shield, and also has a nice amount of HCI for those times when he's out of mana and can't cast LS. If you have to choose between the 2, I'd go with the glasses, as HLD stacks & resets it's timer. Each time you hit with HLD it's an 8 second timer. If you hit again with it during that timer, it resets the timer at 8 seconds. If you have it on both your glasses and a bow, it's pretty much guaranteed that once one goes off, the creature will stay with it on the entire fight.
