There's a vid on the FB page linked above showing Hully Gully at the weekend - basically a muddy line in between frost and snow.
I did a "3/4 loop" on Sunday, basically all the lower loop plus climbing up to the top section bit of fire road and returning along Bottoms. All of that was spot on except for some ice in the trees just after you climb away from the stream on Bottoms.
Met a few lads who had done the whole thing, and they said it was mostly OK.
The new sections are ace, particularly the bit descending away from the skills loop area. Skills loop was fun, needs a bit of time to settle in though.
