You will need some positive incidence on the wing. Aprox .5 deg is standard. 0-0-0 planes need have a few nasty habits like ballooning and poor inverted flight. 0-0-0 sounds good bit it just doesn't work out. There are a lot of very nice flying CA Widebody's out there. I would leave it alone and trust Marcello had a reason for putting in the 1 deg pos incidence.
