ironsidegnr...I basically went down to two in my rotation. Currently I have four. For me, it's a matter of remembering what "stage" I'm in with the various razors and what needs to be done on any razor on a particular day. I really find using one razor for a week or so keeps me on top and is not so demanding in my short term memory. For a while there I had been using the big suckers (a 7/8 Hart and a 7/8 Wostenholm) and found them both great shavers. Then I went to two smaller ones a (a 6/8 Holzhauer and its smaller twin in 5/8) and found I could appreciate the shaves as well as using the big guys.
