This thread prompted me to experiment and I found that
- start from the default positon on the hoods ie the V between thumb and index finger is centred on the hood top
- slip the hand down and around so that the thumb knuckle now rests on the hood top
- this gives better accesss to the end of the lever and hence more leverage
I have not yet tried this in an emergency and I have not attempted to replicate an emergency but certainly this works for me in ordinary circumstances.
