Rickair777 has it exactly right. The 'forward base' concept is the way to go if you're worried about your ability to make a 2 hour callout.

Whatever you do, DO NOT COMMUTE TO RESERVE. I've commuted to both ORD and IAH for reserve...it is a miserable existence and you will find yourself questioning your sanity. Commuting to a line is tough enough... Commuting to sit in a crash pad for days on end will warp your soul.

Trust me.
