Man....You've just opened a Pandora's Box of YMMV....Blades probably more than any other facet of 'Wet Shaving' is loaded with the 'YMMV Factor'.....
I suggest you try all the ones you see people using on the 'SOS Thread'...Then tell us what you think of them...That would be more important...
But for the sake of some suggestions of what to put in your 'Custom Blade Sampler' Heres a link to a test that Gary did on blades...I think its one of the best comparisons I've seen...:
And I guoted Tom above for the best Injector choices....and I'll also add the rebranded Personnas like EMS, Ted Pella, Longs Drugs, CVS, etc. all the Personnas are similar and consistant...especially when compared to DE blades...
