Quoted from Whysnow:
ron does amazing work, but completely not needed on Spooky Pfs.
It is not needed on any PF. Spooky’s Playfields are not magically better than any other. Small differences here and there but very comparable. I will say this though a Kruzman is worth every penny. I myself would do this on a route machine or a machine I planned on keeping for awhile. I know Rons resale is strong but I probably wouldn’t do it if I was only keeping it for a year. Then again if the machine is hot a Kruzman RM will probably be worth a fair bit more than a non Kruzman RM.
