In reply to PeterM:
I did both training and assessment at 'plastic bread bin' (assessment only an couple of weeks ago), I used 2 rucksacs; 35L for mountain days & Pod Black Ice for expeditions. During expeditions most participants 'double up' to share a tent and cooking facilities, reducing the amount you need to carry. For training, you can borrow most gear from their store, though to be sure just give them a call.
Enjoy yourself, I had great times with a great bunch of people.
