I have tried the mighty vac and no matter what it pulls air in through the bleeder for me. That is even with covering it with grease as well as using thread sealant tape.

I just use the 2 person method which is cheap. Quick and woke well.

Down the road I'll likely buy a pressure bleeder but for now the 2 person works fine

I agree mityvac is overkill. Spend your money on something useful!
