Same setup as Fed. I'm not trying doing it just cause he does, I bought a PC600 used once with this setup already in it and really enjoyed it. I'm not a string breaker, so I think it should last long enough to justify the cost. I'm going to put it in my PT280. Gut in the Mains, Alu in the crosses. I'm going for an overall tension of about 57lbs. So based on my searching around here, I thought 57 for the gut in the mains, and 55 for the ALU in the crosses. Sound right?
