Any static unbalance is magnified when the engine runs -
Depending on your idea of good enough - you may choose to leave it alone
This is not an "airfoil opinion" thing - this is real , demonstrable physics.
For me - I want the prop perfect or I toss it -or- I may make a newer prop from larger prop - but unless it turns out balanced and with no blade tracking problems and no tip waver -- I won't use it.
A 22" prop running at 8000 is not a toy-and a 26" at 7000 really has a lot of loads working on it.
Even the electrics - My new Hackers and tiny rewinds show real power losses running crummy props -so they get balanced on a magnetic field pivot balancer . (almost zero friction.)
