I use toaster whenever I have enough ammo to spare, RFs also pretty often if I'm good on health so I can risk getting blown away a bit. When underwater, I use seekers almost exclusively (when I can), and often strategically to hit enemies around corners and stuff like that. I also use bouncer pretty often to not only shoot down holes and drops but also to get rid of some low-height enemies like lab rats or suckers because it's faster and more convenient than ducking

so yeah, I don't really use blaster that much
