Connall,
I like that kettle helm too. I wear one from time to time with a butted, blackened mail coif. I'm kinda in the process of changing up my kits a bit, so it looks like I'm going to be using that head gear in conjunction with a late 14th and early 15th century hand gonner personaes I'm going to be working on. My current Faire helmet has been a Morion, though when my Cabasset is finished being strapped, I'll probably try that out too. You don't see many people wearing kettle helms, so that is why I really like them.
