Much much thanks for both responses.Yep, installed the fatdaddy two magnets as per the rules and it still fires standing up. With his longer contact pin in the bottom which I installed the improvement is only very slight for me with respect to throw and stiffness. Yep, it's magnet time via FT unless someone else can dream up a better solution.
Very educational!
The cheapest route would be to simply replace the spring with a stiffer one. Should be a hardware store around town that has some springs, or you could just make one with stiff enough wire. Shouldn't cost more than a dollar or two.
Not sure I'll ever understand the fascination with magnets. Seems like a complicated and expensive solution to a simple problem. But perhaps that's the car geek in me talking, I can't see replacing my car springs with magnets when popping in a new set of springs would be so much easier, cheaper, and lighter.
