Threw both at a Storm/Roto Open House. They gave me roughly the same number of boards covered, but the Hy-Road was more angular while the Grand Illusion was smooth as butter. Both had the pin directly above the center of the bridge, though the Grand Illusion's pin was about a full inch closer to the fingers than the relatively high pin placement on the Hy-Road, which should account for some of the angularity. However, since the Grand Illusion is 100% solid while the Hy-Road is a 50% solid, 50% pearl mixed hybrid, this accounts for the reaction shape differences as well.
