I use Henson+ and have yet to try a Feather (came in a sample pack) or similar ultrasharp blade like your Wizamet Super Iridium. My blade of choice was Astra SP (Russia) and is now Tatra platinum, with some experimentation with sharper blades (Personna Blue platinum, Personna Red (Germany) and Bolzano). The Personna blades are persona non grata as they were very irritating. The Bolzano has mixed results which are probably soap dependent.
Paul, you should use sharp blades for AL13 mild. It will give you better shave.
