I use the caboose throws on all manual siding switches, which are either Atlas C80 or Peco C55.
Most of my industrial track is right on plywood with minimal roadbed, but where there is roadbed, the 'connecting rod' of .030-.035 brass wire so that the ground throw is low and outside the track roadbed area. Even with the compensating spring, they put a substantial torque to the switch, and I've broken a couple switchpoints with them over the years. The brass wire with a bit of a bend in it acts as a second spring of sorts.
I've also made a practice of digging a hole for the base to lower them a bit on a plywood subroadbed. You need to be able to trip them with a fingertip, but no higher. Lower always looks better.
When you're installing them, I center the points, put temporary plastic shims in to hold them, connect the rods, stand the throw rod vertical, drill .025 holes into the subroadbed and use wire brads for strength. That insures that everything is centered and it's a strong installation.
