I was actually playing with throwing errors at 8 and 9 for awhile. The first so many games I played at default, I didn't see 1 throwing error. I would suggest to try 6 out. Also, throwing errors shouldn't be that bad at 7 (maybe I'll realize it is too high but I'm still liking 7) if you don't always throw in the red (not saying you do but online people do this all the time and end up with at least one throwing error a game).
