We present initial results for light hadron masses and nucleon structure functions using a recent proposal for eliminating all O(a) effects from Wilson fermion simulations in the quenched approximation. With initially limited statistics, we find a much more linear APE plot and a value of the axial coupling gA nearer to the experimental point than with comparable runs using unimproved Wilson fermions.
