Interesting. What this guy doesn't mention whether the spin loss stabilizes over time, just like how strings lose a lot of tension initially then the curve flattens. I can't imagine anyone swapping paddles every 3 months at $250.
And is 1300 RPM vs 1700 RPM a huge difference. I mean in Tennis, Rafa routinely hits 500 RPM more than many other pros on his FH, yet folks compete just fine with the lesser spin? Is it just Big Number Syndrome here?
What I would expect is that carbon fibre paddles will settle in after a month or two of use to a lower spin level that maintains its level for a much longer time. Just like strings on a tennis racket.
Anyways, I got the Franklin Signature on a really good deal, so it's a grit paddle. But at $48, I'm fine replacing the paddle if the grit wears. I can't imagine replacing carbon fibre paddles until they break.
