The Seal 

You don't need any large cams (like #4 or #5 mentioned)

This is one of the sexiest routes I have ever seen! I am heading out to North Carolina for just for this!

Never saw a spot for a #4 or #5, but I would bring doubles of #1, #2, and 0.75 camalots, plus several small camming units. Not PG-13, in fact this route will take just about as much gear as you can feed it. Warning possible beta spoiler will procede!

I would say that the crux was not the offwidth undercling at the top (all though placing gear is pretty strenuous through that section) but the thin section about 1/3 of the way up the route. You will know it when you get there. It is marked by the finger section getting to thin to use (at least for bigger fingered people) and your feet slowly dwindle to smears.

I used a 4 camalot right before the wide section, which was definitely the crux for me.

Great route, amazing moves. Didn't need doubles of anything really. Takes nuts (I used a lot of nuts and tricams so I didn't need doubles) and cams well the whole way.

anyone got beta for the upper aid pitch?

It's not necessary, but you can get a big piece in the right end of the big slot if you want a more directly overhead piece during the crux. It's also a good directional for the second especially if you think they may whip on that move. That undercling always feel super slick and somewhat desperate to me. Fortunately my wife can walk the dog that pitch, so I rarely have to lead it :)

Great route, and stout for the grade. The thin fingers was the crux for me since I'm short, but that made the upper crux easier. You win some and you lose some. I didn't use any underclinging at the wide section, just some crimping and a side pull. No need for large gear, but it would be helpful for your follower.

I noticed the FFA was not noted. It was by Mark Richey in early summer 1976. All these north side routes were pretty sporty in eb's and swamis.
