Quoted from Redketchup:When i did my second Fathom swap, I change all the insert socket for 44/47. I keep the 555 only for the GI. Can i suggest you to do the same, make a big difference with new socket and ground braid!
I also highly recommend replacing the 555 sockets with 44/47. I also upgraded all the lighting braids to 1/8" flat braid..
