Razor 3 vs 4 vs 4xl

[onttr22]

Of these 3 props of Marks which one likes to be run the highest and lowest?

I hear the 3 and 4 are usually stiff is the Xl as well ?

Thanks

the xl is just as stiff as the razor 4, imo. i havent run a razor 3 blade, but i will say the xl likes to run a bit higher than the razor from what ive found.

Dumb question, but what does "stiff" mean?

harder to turn. less rpms that other props of the same pitch.
