Which blade should I try first?

[dzagales]

So I ordered a sampler pack of blades now that I am done with the Derby's that came with my razor. But which one should I try first?
Merkur
Lord Platinum Classic
Wilkinson Sword classic
Kai
Feather

 

[Yuritau]

IMHO, save the Kai and Feather for last, use the other three in any order that strikes your fancy.
