I have to agree also that it's a matter of personal opinion. Research the different switch assemblies, way the mod locks, air flow, no airflow, floating positive pin, adjustable pin, and see which ones you will like the most. I'm not a fan of brass, so I like my mod to be all stainless. I had gone with a Nemesis cause I also liked the option of availability of replacement parts, as well as putting in a magnetic switch if I want to.
