I will answer it here too !
Its basically a regular shooter, with a sexy looking gun on the end of it..
I find the full plunge a little slower than before, but better because now the maelstrom flasher has done its job blinking me before it gets to the upper flipper..
The extra weight makes it so. A stiffer spring will restore original strength
