Welcome to the forum. I’m also a newbie but a long time lurker and researcher of the Wicked Edge system. I bought just the basic kit and have since added the 800/1000 grit plates and an Angle Cube (definitely recommended). I can see that soon I will be adding strops to the system to make it similar to what you are getting.
I guess as a newbie all I can say is that you will love the system and to read all the tips and watch all the videos on the site to prepare. As other members have stated – the paddles take a while to ‘bed in’ so it will be a few knifes done before they start settling down. Take it slow and have fun. (Also keep your fingers out of the way.) 🙂
