I think the thing is to not turn up expecting imaculate trails, nor is it really worth it as experienced djers to turn up and expect to session for a day, but as a place to learn he to jump, and deal with pumping speed from downramps its pretty good. The pump track is abit of fun too.
Its not on the same level as oxy (better than the old grove imo, haven't ridden it since some guys have been working on it recently though), redhill etc but I wouldn't be comfortable taking someone whose new to those places.
As some jumps to hit after a couple of xc loops it's pretty good. And my girly quite likes hoonin around the place on my bmx so as for that purpose its pretty mint. Nice tables to sit around, bike wash bays etc. to make a dedicated dj day though its abit crappy yeah, but not rubbish.
The awkwardness of the place means you have to work harder to clear the sets cleanly, but transfering between the lines can make holding speed abit easier. These are good skills for people to learn, rather than just plow through without having to think, just hop and rely on the upramps to send them the right height/distance.
I don't think writing the place off completely is really fair, for a council built place it's not too bad, especially compared to some other places (mortdale for instance, if anyone remembers what they used to be like, and the pitiful 3 mounds they replaced it with).
