Cathedral is my favorite trail at Belle. Thanks for posting this. I am heading up on Thursday (and maybe Wednesday night if I will be the only one at my favorite low frills ski club) to take a day off to ski near my bday.
There is another all-natural trail called Utsayantha that is only open on natural snow that might be the steepest at Belle (groomed or ungroomed). And while folks make fun of the short steeps at Belle, where it is steep, it can be pretty steep. It looks like it may not be open, but that is a fun one when there is enough snow.
JTG - Belle used to be very good at opening a fair amount of trails with bumps or natural conditions. That changed initially after the Gondi went in but seems to be making a come back. There was a year or two where they groomed out all bumps everywhere, which was a bummer. Good on Belle for bringing bumps backed. Looks like they are bumped/ungroomed on 3 or 4 trails right now.
I love Gore, but I was surprised by the lack of bump runs when I have been there. May be the answers is that they open a lot of glades. I haven't been there too many days when the glades were skiable, but when they were they were great.
