The turbo sled still feels heavier but after adjusting the front skid shock tighter to take some weight off the skis it is pretty good. I'm sure the 3.25" lug track makes a huge difference in the feel of the sled too as it does have more traction. This is good for lifting the skis but also makes it feel heavier if you don't grab a handful to get track slip when initiating to get the sled on one ski. For those guys who bad-mouth the 2.75" track, it works very well for a lighter, lower powered sleds as it allows some slip which is huge for improving maneuverability. I am way less tired after a day on my NA over the Boost and it is not all about more power and more weight.
