I am using a horse butt strip of my own make. It's broken in to the point that anything I get or try doesn't work as well as it does, and that included a kanayama 80K that I had - and a strop of my make with a horween shell (which was nice with the factory finish on it, but spending $200 on a shell to make a strop turned out to be a waste of money). I used the kanayama a little bit, but the leather wasn't hard enough that it would've gotten up to the butt strip strop that I have, and the linen didn't match the vintage silk finish linen by a gigantic margin (actually, I never ended up using the kanayama linen because of it).

In the end, I can't deny that the kanayama was a very nicely made strop, but it didn't have any magical powers that a good vintage strop or a good well made piece of literally cut leather would have itself.

My butt strip strop cost about $10 to make (I had use for the butt strip leather remaining around the cut-out strop elsewhere, the whole cost of the butt strip was $30 - enough that it would've made two smooth strops, and the only detriment is that I had to break it in by stropping a junk razor on it once a day for a month before it settled down). The separate linen I found on an NOS illinois strop from the 40s and it was another $40, but they can be had for less than that.

Your red imp broken in is basically what my combination is, if the leather stays the same. A great strop is partly manufacture and partly what you condition it to over time. Once you have a daily user broken in with a routine, you won't be happy with anything else. The only way to avoid that is to buy and use so many strops so often that you never get used to one.
