Simple, as Eculid said, one layer of tape has never harmed a razor :) No tape has harmed millions
Use tape until you are leaving no wear on the tape than do whatever you want
Also before somebody says "If you use tape you must keep using tape" watch this vid of me being a complete smart ass because I was sick of people saying things without ever trying it :p

Multiple layers of tape are only needed AFTER some ham-handed gorilla has destroyed the spine :p
Hone On!!!
