So I ditched the r41 9 shaves ago. Since then I've gone back to the EJ89 and have been using one shim and I must say the shaves have improved. Going to try 2 shims on Tuesday. I would have to recommend it though to anybody looking for a closer shave before investing in a new razor.
Just goes to show how very true YMMV is!!!!
