Thanks for the pointer, they do look really good.They don't make an m444. But the short zip version Anj4 with the two buttons is identical to the m445 a. The long zip version is the standard Anj4.

Does your recommendation mean to avoid the 444s in general? An ANJ-4 is on my list eventually, but currently prioritized behind one of the shorter-pile models, of which the m444 is the preferred one.
