I have a hush in my zenith and it doesn't make much of a difference at all. However, the difference the zero makes is pretty significant.

ZeRO, u cld feel significant difference with it.. I had used Hush bolt, one or two times I leave it aside, does ntg significant & extra care for its orings.. Why hassle?
I dunno what you guys are talking about, I noticed a lot of improvements with the hush bolt, and how hard is lubing 3 orings? Takes 30 seconds. I haven't tried the feather striker yet.
