Oynx summit is a fun trail to get you warmed up. Great for 33"s. Finish that day with Tip Top Mountain to get the best view around.
Depending on the number of rigs that will be present. Multiple runs can be accomplished to include Gold Mountain, John Bull, Holcolm Creek, and Dishpan. If more than 10 rigs, you can still do two out of the four runs. I've done all four with three rigs, but it was a full day.
At Big Bear Forest Fest , I led a run to John Bull with 25 rigs, that was an all day event in its self. We had a minimum of 33" and one locker. I've been on it with rigs with open lockers. Just be prepared to use straps to pull rigs through.
