Its the best option. You don’t need to do it for all the panels. Make use of the cave and the everest wall as well. Once people have done all the stations then they can climb on the remaining panels. Is there anything wrong with doing it this Tuesday? Sooner is definitely better than later.
In terms of leading, there are people who join who can already belay but haven’t lead. We can start off teaching them and the more comfortable people get with belaying, the more people we can teach. Ideally you want the people who are interested in Spain leading before christmas as it gives them time to get comfortable with leading before Spain and it will be harder for people to get down during the exam period.
