You should hit the gym.
I've owned my fair share of Subaru's, putting probably close to 500k on all of them combined. Never once have I used any kind of tool to install an oil filter, and never once have I left a trail of oil caused by a leaking filter. That's around 170 oil changes without a single hiccup, and that doesn't include the hundreds of oil changes I've done on other cars.
As for removing a stuck filter, a screwdriver never fails.
