Narrowing down my choices of options on a new GH, I plan to add the extended levers and suspension seat. Someone posted on this site a few months back that the extended levers made the levers stay open 4". He said there was a 4" gap between the levers and he could not operate with one hand due to this. My dealer dioesn't think the extended levers affect the gap between them. Can anyone else chime in on this for me? Thank you.
