Need some help with my speedy lab guy

https://pastebin.com/cmgMYRFG

I am lookin to farm uber labs with the pathfinder, I have taken some of the ladder builds and modified them to be slightly safer, however Im still dying Im 0/6 dying to izaro only so Im getting pretty desperate. I have no interest in getting top tier ladder, Im just looking to be able to farm reliably. I have liftings totem slayer which is very safe, but the speed isnt there. Would love some help.
