Thanks for the reply, Rich. Felt a bit uneasy about deviating from Leonard's plan so went ahead and followed it for the first of the two Rear Main Spars. Came out fine. Wondering if Leonard's idea is that it provides load spreading and reinforcement for the wing strut. Seemed logical to me so, with no other experience to draw from, just followed the plans.
