Hi!
I could really use some help here.

I am a total rookie at this straight razor thing, so maybe I am just expecting something from this that is quite simply not obtainable. Or I am doing something wrong

I have been shaving with a shavette from Feather for a couple of weeks. It's going good, not too much blood drained anymore
But it's kinda hard to use this razor, I really have to be very careful with it, It's really unforgiving. But extremely sharp! (professional super blades)

Now to my concern.
I just got a new Bergischer Löwe. It is a very nice razor, really smooth and compared to the Feather, very forgiving. It's been professionally honed and all, but to be honest, compared to the feather thing, it feels damn near dull.

Espescially when shaving my head against the grain it really pulls and sort of jumps on me. I really have to use a bit of force to get trough the hair.
And the shave is nowhere near as close as with the feather.
My other razors are a couple of Filadelfias, and it is the same with them, the Barbas Duras is somewhat better than the rest, but not what I would call BBS good.

I'm probably doing something wrong here, but cannot for the life of me figure out what.
I have been experimenting a bit with the angles of the blade, different oils and soaps/creams, but as for now, without any kind of success.
I know my stropping isn't the best, but I do 20 laps on the nylon and 50 on the leather strap each time I shave. The Bergischer is kinda funny, it sings sort of when I do it.

Any kind of help or tips would be greatly appreciated.
