The Jet Fuels are considerably stiffer than the Nitrous. The Nitrous was the Carbon version of the Top Fuel. The Top Fuel was a similar build to the Jet Fuel, but was 78mm to the Jet Fuels 84mm. The extra width in the same build stiffens things up and the build with 2 sheets of metal is always beefier than the Carbon option. I skied the Top Fuel and really liked it. I passed my level 2 ski test on it in a 170 on a powder day. The Jet Fuel is burlier than the Top Fuel.
I agree that a few lessons should help. I skied lots of bumps on the Top Fuel and even more on the Jet Fuel. Neither ski is ideal, but both will work fine if you are a solid skier. I probably have about 125 days on my Jet Fuels.
