I started with an EJ89 and tried numerous blades: GSB, Astra, Personna Reds, Derby, Feather, Kai, Gillette 7 O Clock yellows and the 7 O Clock Yellows were the best in that razor, but only seemed to last for 2 good shaves. Feather, KAI, GSB and Derby were incredibly painful, Astras were good and the others were sort of a "meh" shave. OK, but not all that great. Got a Parker TTO 27R and a Parker 24C Open Comb. Parker TTO 27R worked OK with some blades, but felt the same shave wise as my EJ89. Then I went to the 24C. What a difference! Tried Crystol blades, meh, Gillette 7 O Clock Greens were pretty good. Shark's were awesome and the Lord blades I got were horrible. Put in a Gillette 7 O Clock Yellow...ahhhhh. 5 great shaves with it and it doesn't seem to be losing it's edge yet! Barely any weepers, and even the bumps on my face that usually get teeny cuts on them weren't even bothered! Feels so smooth when cutting, no irritation either.

Gonna order up some Sharks and Gillette yellows in bulk after I try the Astra's in the Parker 24C, but those are the top 2 blades so far. Such a nice thing to find the razor/blade combo that works well with your face!!
