If you want to fly 6 up most of the time you would do better getting a Cherokee 6 as they do have the bigger load capacity and book states only 5 or so knots slower.
Some would argue you can not see the folding wheels anyway when you are driving the machine so who cares!
However the Lance with some go faster mods (on the 'N') will do 160KTAS @ 8000ft so that is quite nice.
