longer wheel base true but having no rockering in the skates means they won't carve, most likely they are being turned by grinding the front wheel
sideways ever so slightly.
a four wheel skate turns on the rocker more or at least they help to pivot the skate.
there is a French designer (Carvel skate) he is making a 2 wheel skate that has the rear wheel pivoting slightly pretty cool.
my solution is just to be up higher with 4 wheels. they work well, with added penalty when falling being higher. The added wheels also help to
float over uneven terrain. They have more drag, need higher wind. I like the ski boot though very confortable. Intermediate boots have lots of
flex.
They track less as Bob mentioned. Strong wind you get pulled off course probably more than some would want. However the added maneuverability is
really fun to have. I can make a U turn in about a 5 foot area, sliding the back ends a bit.
