Last time I did it, I think I led all 3 pitches in about 2011 or 2012 or so. P3 is definitely a step up from P2. In the beginning, it is not too hard but scary because of potential fall into the abyss with crappy/no pro. I remember applying way more pressure than necessary on the back/knee moves out of fear, and then getting out of that to a stem and transition to just the one wall was committing. Then at the top it gets more technical than anything on P2, but fortunately the pro is good at that point.
Edit: I thought I found a picture of it, but this doesn't look quite right... if this is not P3 of Reed's Direct, what is this? Could it be something like Harding Chimney at Sugarloaf?
