Demo or Performance Rental

At what skill level would one be able to comfortably rent demo skis as opposed to the typical performance ski?

For context, I’m an ice coaster, only ever skied fairly narrow/typical rental skis, heading to Breck for a week and deciding if I should go for demo skis.

I would say I’m an upper intermediate, all blues, groomed, ungroomed, moguls, ice, I’m feeling pretty confident. Black diamonds are fairly new territory for me but I’ve felt comfortable on those as well.

Bit worried about skill regression, I guess, if I were to give all mountain skis a go, since I definitely want to explore the most terrain I can while in Breck (though probably not the bowls on this trip). But also wondering if now is the right time to give a different kind of ski a shot.
