I can't contribute anything as to what will/won't work for you, all things shaving have always been tagged with YMMV. The DE benefit argument is valid as far as I'm concerned. The FACT(s) of the matter is:
1. Single blade razors ARE sharper and less expensive than multi blade cartridges
2. Proper technique + razor selection for your beard type + blade for your skin type/hair coarseness/growth pattern + correct product properly lathered and applied to a properly prepared face will give you a closer and irritation free shave. This is NOT subjective, it is objective considering the amount of positive feedback from a large number of veteran DE shavers. (Ask Turtle. He has more experience with DE in his little finger than the entire shave clinic combined... I am convinced he can get BBS with a butter knife taped to a rawhide mallet lathered with Cool Whip)
