So I shave primarily with a straight and have a gilette fusion right now that has only been used a few times since Feb when I began using a straight. I still have a bunch of blades for the fusion but thought I'd maybe invest in a DE as a backup and just have a box of DE blades for when I'm trying to get a quicker shave (I'm assuming one can shave with a DE faster than the straight) or maybe touch up though I don't do that, at all, right now with the fusion.

What should I be looking at when I look for a DE? I've been mulling over maybe another purchase from SRD and so I saw the Murkur ones there and thought I might buy one with some of the blades with my next purchase there, probably just the CF Limes cream and a/s balm but potentially a vintage straight too (just got the CC paid off ). Any suggestions on what would be a good DE to use for such a purpose? What is with the differences on them. Thanks any help appreciated.
