Those were the same issues I was having. In addition, just the slack feel from it sucked. There are a couple corners we have at a local track here where we short shift while leaned over, the lack of a solid switch often left me wondering "did it catch?" In the middle of races, I don't want to have to think about how hard I need to press down.
With the WR switch, there's no question at all! Love it!
Although, I am yet to really mess with the kill times enough, I have a little bit and haven't found what I like. You mind sharing a range that you seem happy with for comparison purposes?
