A ss prop won't flex under power maintaining its pitch. You may have to go with slightly less pitch. You might even get a higher top speed from your boat
SS allows more cup allowing you to trim out more which provides more efficiency.
It is heavier so it works better for slow speed trolling as it acts like a flywheel smoothing out the engine.
That flex is a big factor. Tuning a known is easier than guessing the flex. They're also a bit less drag, more aqua dynamic.
