The Onion River Road segment is in fine condition: good skis would be fine. Trackset and skating lane are well set for the full 5.5 km out (and the same return). There were a few short segments on the east trackset (right-hand side when headed down) where it seemed as if there had been some instability in setting the track, leading to a narrower track, but not bad.
The western part of the Oberg loop was also groomed with trackset (2.4km), but there were quite a few (maybe 10-12) short segments (a few strides only) in which there wasn't enough snow to get full coverage for the track. Easily avoided, but there was enough other small shrub poking through that it I'd put it in B ski condition.
The eastern part of the Oberg loop and connector to Picnic had been rolled, but not packed or tracked. I went a bit of way on the eastern part of Oberg and the snow was quite soft. Enjoyable and good coverage for the short distance, but I don't know how things would be for coverage along the length of the trail.
