Peak movespeed build for farming UberLab?

Hey all, I currently run the King of the Forest Assassin build to farm Uber Labs. I've been enjoying it plenty but am curious if there is anything with more movespeed that is viable to farm Izaro?

Don't get me wrong, it's fast but...
I want faster?

QOTF Pathfinder is probably the fastest you can get. Massive flask effectiveness, with jade flasks, and QOTF, etc. realllly go go goes. Many of the lab racers run a QOTF pathfinder, with a separate 6L chest in their inventory that they swap in for the izaro fight (like a +! tabula) with a mine setup to one shot him.
