Wait..lemme clarify what I meant about the tough part..lol.

One night I was slightly inebriated and, while walking up to my apartment, I dropped back behind me and down the flight of stairs. Not a single ding or scratch on the frame.

I guess when I see quite a few of my friends' bikes that have been dinged up from having been dropped..I consider the SE frame tough. Maybe not tough by you guys' standards...but for my purposes...

I should also clarify the purpose of this build. I need a commuter/beater/utility bike that is very comfortable to ride but still able to be abused without worrying too much about it.
