I have the 5/32 gear on mine and have had no problems with it. I fly from a fairly smooth asphalt runway, however, and grass might put a little more drag on the gear. I would also suggest that you consider moving the mains much closer to the CG than the plans show, to avoid the "stick to the ground" takeoffs, requiring a lot of up elevator to rotate, which then gives you a "zoom" takeoff, not good, not scale. I know this from my old pattern plane days with trike gears, plus a fellow club member has built two of the Wing A-26s, and moved the gear up on the second one to avoid such a problem.

I set my nose gear by attaching a Robart incidence meter to the wing, and adjusting the nose strut until I had a 1 degree positive reading. A negative reading will also stick the plane to the runway. OK for landings, bad for takeoffs......
