What is the best ammount of mf?

Ey does anyone know around how much mf is good for pindle and meph?? i have around 350, and dont get that great of items... should i use less or more??

They say the about 500% should be good enough. It's a nice half way point. I have 540% on mine and already I have close to 300% UF (Unique Find) with it.

i had 460 mf (cuz of dual occy rings)..and i found enough shit cuz i did fast runs..i recently switched to 1 occy ring + 1 bugged con ring (so now i got 644 mf)...i have found less shit cuz i do less runs...more runs is better than more mf..ESPECIALLY for pindle/meph bot

haha aite.. i guess ill just stick with my mf and do alot of runs... they if this fails i'll raise my mf
thanks
