Wah pot values?

[Zork]

So, I need to replace the potentiometer in my crybaby. It's dirty and noisy. Now, there are replacements in several values available, starting from 100k over 125k and 150k to 200k and then there's the dunlop hot potz with 470k. Can anyone tell me what's the difference in sound? I like a wide filter sweep and a vocal-like "psychedelic" sound that goes well with fuzz.
