Oil drain plug rounded off

[peanut]

I think I've officially rounded off my oil drain plug bolt. The 17mm socket slips right off. I have tried hammering it (wow, no space for this really), channel locks, and a rubber band in the socket. I can't see how to get a wrench in from the side, though its claimed in this link:

I'm considering getting a rounded bolt set, but for $30 and no garuntee of it working I feel better off just taking it to the dealership and getting a new bolt while I'm there. I'm probably taking it there in a couple months anyway for a professional eye to see if I'm missing anything on my maintenance.

But I haven't given up yet!

So first of all, am I turning in the correct dirrection?? I am on the right side of the bike (with the oil filter cap) and turning the bolt towards the back of the bike.

Is it THAT bad of an idea to drain it through the oil filter compartment?

Would I do any real damage riding it ~90 miles before changing the oil? I changed it at the begining of last season (no problem with the bolt...) and rode just over 1000 miles.

Thank you all for any help.
