Hi Rob. As Ripper says, the Sellaronda is easy cruiser, infact I say some of the reds on it are only given red because it puts off people who really are not yet ready for the distance involved from doing it.
So where to go for harder skiing. Firstly take a look at my guide to some of the main resorts in the area - they are based around our accommodation, Casa Alfredino, but my Wild Pettorina is a purely informational site. http://wildpettorina.com/sports/skiing/
For steeper skiing, Arabba is great, there are some very steep blacks there. In general it is by far the best spot for steeper more advanced skiers in the range, but by no means the only one. The Gran Risa down to La Villa is one of my favourite runs. Also some of the outlying, unconnected areas are worth visiting, as they are quieter (by a large margin) and have some really excellent runs. For example Falcade San Pellegrino has some amazing side country skiing of the summit dome of Col Margherita and its lower twin summit. A really excellent place to get to grips with offpiste as the geology makes it a more open, slightly lower angle area with less narrow gullies like the rest of the range.
Also Civetta is worth visiting if there is lots of snow (so far looking great this year) as here you will find tree skiing and allows for off piste runs in murky weather but with enough visual contrast to help find the way. On a sunny day, skiing beneath Civetta is utterly awesome.
Marmolada if you get a decent dump of powder is great too - I have detailed quite a number of different routes to descend, the only downside is skinning back to the lifts if you go down to the dam end of the reservoir.
But the greatest single thing you can do if you are a competent off piste skier is to do any of the runs from the Sella Plateau. Take the lift to Piz Pordoi and you can run Val Mezdi, Val Lasties, Val Setus or off the top of Piz Boe. They require varying degrees of skill, Lasties is the most straight forward, but the scenery is utterly stunning and you will remember them for the rest of your life.
