When it comes to aftermarket arcade stick parts, Japanese arcade parts manufacturer Seimitsu is usually an alternative to Sanwa Denshi. The latter company caters more to general arcade stick users, with the former more for those players with specific needs. For example, the LS-32 lever, one of Seimitsu's popular products, has a distinctive feel compared to Sanwa's JLF. The LS-32 is also different from that of other Seimitsu levers, including the recently released LS-62-01.
Judging from the specs, the LS-62-01 is sort of an amalgamation of previous levers. While past Seimitsu levers were mostly different from one another, the LS-62-01 seems like more of a greatest hits lever. However, it still seems to carry the uniqueness the other models bear for better or worse. It feels like an experimental design, but for what it is this new lever is pretty capable.
