Ive been using the feather and the CJB clone for awhile now. My suggestion, if you have them are the Proguard blades. Find that with these I have very few problems.
If your using the professional blades, I found that at 1st I did have to 'stretch' the skin a little to avoid scraps.
Soap was also a big factor. MWF ( or the like) would be a good starter.
(Don't start and stop without lifting the blade. I try to 'hit the skin moving'!)
Good luck!!!
