A GON-based GB would be very nice, albeit not to convenient for me in the near future for personal reasons; but in later rounds, I'd love to see a GON-based 60% GB repeated, if the IC is successful.
I also added to the form, my interest in seeing lubricant added as an optional part of the potential GB, as it's difficult to get a hold of any suitable lubricant in the UK, with ease, let alone the most preferable options.
