You want a gear that you can spin at least 135 in for several minutes, well 150 really.
At the moment, i don't have any space cogs for me to play my GI. I only have 48x14 atm. And i once climb a mountain that is very steep but don't know it gradient, you you can really see its like a ramp until the end and i rode that until to the top with a 80 GI! it was very tough hahaha
