I like non-adjustables because there are two razors set just like I like them. The Merkur 34C is middle of the road, not too mild and not too aggressive. The Merkur 37C (slant) is the best razor I have ever used but sometimes I don't want something as aggressive as that.
I have one of each, which covers all my needs and desires.
For blades, my favorites are Medical Personna and Astra Superior Platinum, because I have never had a bad one. Occasionally I like to flirt with a little more aggressive blade so on those occassions I use Feather. I never had a bad one of those either.
With a DE razor I like a shave stick with a best badger brush. (When I shave with a straight I'll take a thicker soap or cream with a silvertip badger brush.)
Part of the fun of this is figuring out what works for you. :y
Anything beats the shaving equipment you find at a drug or department store. My face was riding on 40 years of bad road when I was using that stuff. :cry:
