I would say get Mog Fork, dump acc necklace (it's terrible) for a Gorget HQ. Yes, Lieutenant Trident is better, but it may require more grinding so it's all depend on you. Your current setup doesn't have much STR/PIE to tap in high DPS stat, so don't worry about it much. I use Explorer Moccasins (with Explorer Tool Belt as well) in my build mainly because I focus on Crit ATK as much as STR (343 STR 290 PIE +135 Crit Atk), but for your build just use AF feet.
