yes - i do that (- not sure you have to be "less tall" for that to be effective mind)
My daughter has been doing alps trips with me since she was 11 and is a very experienced co-pilot for this!
(- shes 22 now, and, sadly, i suspect this might be out last daddy-daughter trip for a while as she will be a junior doctor next year and enter the world of 'work'
