The slower meter has benefited me. The rest of the charts are the same but meter increments are not.
The redwood putter has meter increments of 15, 30, 45, 90, 150, and 300ft.
The Rossa putter putter has meter increments of 15, 30, 60, 90, 150 and 300ft.
I have owned both and I prefer the Rossa!
Cheers
