I guess this is why there are different strokes for different folks...but IMHO, the feathers work pretty darned good in the Merkur Vision, Progress, and Fatboy, which are my regular DE razors when I am not using a straight razor.
I just shaved with a Tuckaway and a Feather. I now have no whiskers and no afterburn. The alcohol based A/S almost made me wanna cry but that went away. I'd say its a go on that one as well.
