I've never looked into getting a SLOC, thank you for the heads up.
It shaves similar to the yaqi Mellon. Used the Mellon yesterday and the SLOC today. Both pretty mild. If I had to pick between those two it would be the Mellon only because I could get it in stainless steel.
However, I did get the SLOC recently because I found out, @never-stop-learning, that I can Frankenrazor it with the R41. That was worth the $10 for the head.
If I had to pick between all my double opens it would be the PAA Ascension in what ever metal they have available or that you prefer. It's a completely different shave. The other two are similar to the original Grandshave King. The Ascension really puts a big curve and tension on the blade. I feel safe twisting back with it to make the razor much more aggressive. 1/2 turn back and it's really efficient. Snugged up and it's really mild.
