Completely opposite here, pla is a dream to print, sticks great to glass with a coating of elmers glue stick, no curling what so ever and it's smooth as glass on the bottom.
Heat the bed to 48C.
Don't do anything special to store it other than leave it in it's sealed plastic till I need to use it otherwise it hangs on the rack above the printer.
Used a bunch of different colors from reprap walmart from china, I use 3mm, the stuff has printed great.
To each his own.
