How about a short cable to a box on your belt? Maybe a vest for extra tactile feedback. Or even just putting all the heavy stuff like PCBs, heatsinks, and batteries on the back of the strap to balance the screens and optics on the front. My little Petzl headlamp doesn't mount the tiny 23g battery pack on the forehead due to balance and comfort concerns, I can't imagine the Simula fares any better!
