I have long legs with a 34 inch inseam and being 67 years old set them as far forward as allowed and found that to be really uncomfortable. So I took them to the first setting closest to the rear and those now are a lot more comfortable than before. I think they need to be drilled and a peg inserted from the bottom to make them easier to open with your foot because right now you either have to open them before you start your ride or reach down and open them while moving and if you don't have cruise control that would be a problem.
Also you don't want to leave them open when the bike is unattended as if it gets hit and tipped over with them open it will do major damage to the valve cover and is going to be expensive to repair.
