I have an 8x10 Hobo with a 120 SA in helical. A 75mm hyper-version would be fabulous. If it can't be done economically in wood, maybe something 3D-printed.
Alas, I'm not going to be much help for now as it's unlikely that I'll have budget for one any time soon. But I hope this comes to fruition and I'll be watching with interest,
