Actually its not the light weight that makes the shifter "lighten up". 
Red Line alters the coefficient of friction of the fluid so as to make 
the synchros work better. Think of the synchros as little clutches. Just 
as in the operation of a limited slip diff, the fluid's COF will alter 
how the synchros (or clutches) engage. The better the synchros engage, 
the quicker and smoother the shifts. Even the lightweight MTL will far 
exceed the load carrying and high temp viscosity of the petro gear lube, 
so you're fine with the thin stuff unless you endurance race or somehow run 
the trans super hot all the time. The advantage of the thin fluid is it 
flows so well cold. This means that even in cold weather your tranny is 
lubricated as soon as you start moving and the car shifts well right 
away. If you've ever had a trans that shifted poorly at first when the 
weather was cold you know what a pain that is. Its not good for the box 
either.
