Well.... After playing with Bori from the Sharks CC, have a look at what she uses... Invite her to play... gl hf.... ;-)
The Rossa is great putter for miss-ding putting, which I do most of the time, I grabbed the Odyssey because I'm starting to move the arrow a bit more so wanted the forgiveness, which helps a bit I guess. I also like the way it kind of leads the ball off the face a bit more, plus it's the putter I use irl.
Putter's mean almost nothing in this game, it really just comes down to what you're comfortable using and are consistent with. Getting a top-line putter won't make you a better player. Really, learn to use your irons n wedges properly then putting isn't such a huge deal.
If you're 1yd to pin, putting is moot at that point. That of course is much easier said than done.. LoL
