Thanks for some really good advice. I think the best course of action for me is to make a scaled down version of the checklist (you are right about the 'to do' list - my club checklist is a book of nearly 20 pages!!)
So I think if I scale it down to what I forget and what is really important and can put it on my kneeboard, it will sink in much better (and my map won't be fighting with my checklist for space!). This will also help me to try and learn the sequential approach, working from left to right.
Thanks again for the help.
