advice
thanks to all of you - I am not sure how I am going to ask my guy if I can try with one foot - I reckon I will be solo straight after that as he will climb out. He is about 6ft 5 and his one knee hangs out the door which he takes off most of the time and the other is on my lap so no wonder I dont try his posture - my knees are close together and back reasonably straight - I will try that and if you guys are managing in boots and whatever I will stick to what I am using for now and try and sort the brain out. I will ask about the one foot experiment.
