A stronger torque spring will not let you take off until you have a higher RPM going so you will feel a stronger take off than lighter weights. Lighter weights will let your motor rev higher but you would still take off at a lower RPM.
Somebody correct me if I am wrong on that.

You are taking about clutch springs I am talking about the big spring in the middle of the rear pulley.

That spring is for higher belt tension, necessary sometimes if you have a BBK, or larger bore engine, and take off power is so high that the variator slips.
Generally you will want to keep the spring as low as possible, without the belt slipping.
Belt slip usually happens with either the belt completely at the lowest, or highest gear.
That spring is balancing out the roller/slider weights, so if you increase spring tension, you should also increase roller/slider weight to get same performance.
You could also increase the spring's tension to stay longer in lower gear, instead of using lower weight roller/sliders.
The good about heavy spring, heavy weights, is that it's easier to balance your bike to run optimally. The bad is the heavier the springs and roller/sliders, the quicker the belt will wear out, and the hotter your CVT will run (and the less efficient you'll ride)

For me the stronger spring holds rpm better on hills the rpms don't drop near as much which results in better hill climbing needs heavy weights and I lost mpg
