Just realize that if you do a NOBO leaving in May, you will feel the pressure to get to Katahdin before Oct 15th. If you are fine with pressure, and relaxed about it, no biggie. If the pressure will degrade your hike, think about going SOBO or a flip-flop (although you already said you didn’t want to do this, which indicates to me some Type-A personality, which indicates to me pressure to finish before the deadline will be overwhelming).
You really don’t want pressure out there. It’s hard enough to hike 2200 miles, you don’t want to have to think “If I don’t do 20 miles today, then I won’t get to Maine on time. I might as well stop now…”
