Joe,
If you are not a total purist use scent on the glow bugs.
I have also tried to hook fresh springers on a fly without any success. Ive caught alot of fall chinook with flies. Im sure its because fall fish are a lot more agressive.
If you get on some fish let me know how you did it. Fall chinnok are the oly fish I chase with a flyrod, I would like to get on some springers too.
Good luck
