What is Ruby Bowl equivalent to?

Never ventured into Spanky's yet since you have to commit once you get in there are there's no easy way down. I'd consider myself a strong intermediate skier that feels comfortable on single black off piste terrain and have skied a significant amount of this type of terrain on both mountains. This season I am trying to progress my off piste steep skiing skills and trying to work my way up to be able to ski Spanky's. From what I gather, Ruby Bowl is the easiest and most straightforward option in Spanky's in terms of navigation. It's also the only area of Spanky's I desire to ski - Diamond and Sapphire just look too sketchy to me where I know I wouldn't feel comfortable, regardless of my skill level.

So my big question is what line/bowl/route would you recommend being able to ski before giving Ruby a try? In other words, if you can ski __________ then you should be able to comfortably ski Ruby Bowl.

I will likely try it for the first time with a lesson or doing an Extremely Canadian clinic. I have a couple friends who would take me in there but I don't trust their judgement.
