I certainly believe success is in just going easy, no matter what blades or methods you decide. The modern cartridges try to make that easier for us, but they clog.
I was too chicken to try the straights.
Whatever you choose, just go easy, no pressure (literally, don't apply pressure to the blade), and it all becomes so simple so fast, I wish I had learned that a long time ago. I would have saved so much money.
I'm glad you are enjoying the den! Enjoy it while you have it, and only pass it on when you are through with it. There is a lot of stuff in there, and it takes some time to sample it all.
Cheers!
