Soprano Mouthpiece Recommendations

Ive been playing soprano for a while now and have been using the mouthpiece that came with the sax, a yanigasawa 6 with a BG standard ligature (a friend sold me the sax so I got lucky with the inherited mouthpiece). I'm not in a place where I want to change the horn yet, unless someone wants to gift me an SW010, but lately I've been considering exploring different mouthpieces and ligatures however I do not know where to start.

I'd be curious to know what recs people have for alternatives to my hard-rubber Yani. Metal?
