I think if he was mine, I would just finish it off and start over. Hey, less to groom, right? LOL. You aren't showing or anything in the near future are you? If not, then no worries, go ahead and chop it off. If so, you might want to leave it and use some of the above methods to make it not look quite so blunt. I think if you were to arch it in the middle just a touch, he would really look spiffy. But like they say, it's just hair, it will grow back..........eventually.
