Hey guys, I started straight razor shaving this past november. I love it for the most part...still having issues with my neck line and jawline, but I'm sure practice will make perfect. I have two questions.

1) It's been about three months and I was curious about honing. My razor seems to be slightly more dull than when I started, but that could be from bad technique. I found this link on the whipped dog site and was wondering if this would be appropriate. 12000 grit. I saw Lynn's video about honing and am wondering if this hone would be ok and also, is slurry just cold water on top of the stone?

2) I bought this bench strop from star shaving and its only english bridled leather. Do I also need to do felt as well? Or is just the english bridled leather good enough by itself? If I do get a felt one, do I need the chromium paste?

I looked at other threads, but seem to be a bit confused. Thanks in advance!
