I have been using my NEW OC lately and have found really sharp blades that work well on other razors work good, but are what I would call harsh. When I throw in a "dull" blade that works terrible in my other razors, it performs like a champ. So I guess for me, with the NEW OC, the cheaper blades are top performers. Might as well save a bit of coin if cheaper ones give a more comfortable and just as close of a shave!
