All that have been built to data have been 1 degree and nobody's complained yet. My fuselage is right at zero degrees at low altitude wide open with one degree. The question might be "how often do we fly at low altitude wide open", and my answer would be almost never. For that reason, I don't see a problem with 2 degree eithers, which would give you a slightly better view over the cowling, if nothing else, with little if any drag penalty, unless you spend all of your time doing high speed passes at sea level. On the other hand, if your aft spar is already glued in place, you can leave it there and it becomes a no-brainer...
