I've been wet shaving 4 months now. I'm using an EJ DE-89 with the diamond knurling and very much enjoy it. I believe I've already fallen into the rabbit hole as I've also purchased a Gillette Slim adjustable. But part of me wonders if it is too soon to change things up with a variable razor before trying out more blades. So far I've used Feather, Astra SP, and Personna Platinum blades. I have 4 other blade brands from a variety pack. My question is should I go ahead and load the Slim with an Astra or Personna (both blades I'm comfortable with now) and give it a whirl, or should I continue using the EJ-89 and get experience with more blades before moving to an adjutable.
