I agree with Buzzard Bait. Because it is a low wing, it is very easy to shim the back of the wing for some positive if it is needed. Another thing to remember is incidence numbers of 1-2 degrees are talked about on WWI craft, biplanes and Cubs and what have you but the ball game changes with planes like the chipmunk that fly fast. For example, I've an old D&B .60 size P-51 with a HB .61 that pulls it as they say in Texas, right smartly. The wing is backwards meaning that it pins in the back and bolts in the front because of the scale radiator. Just a little tensioning difference on the bolts makes a significant trim difference at the speeds it flies.

I'd be hesitant to put 2 deg in any plane that flies fast.
