Two transmit diodes per head would be good for poliscan, one straight ahead, and one off axis by 35 - 45 deg. That way, we could mount the heads straight (parallel) and level, and still maintain good h/h and poliscan protection. The reception angle on the receive diodes would still need to be up to par to receive off axis poliscan though for rear facers.
