Odyssey Exo Putters | Golf Monthly

I've had Odyssey and initially liked it. It was a good few generations ago - the Versa. But ultimately I felt it was not responsive enough to work for longer putts and I prefer putters without an insert.

Interesting though that Odyssey seems to be the most used putter on Tour and plenty of guys use them who don't have Callaway equipment deals.
Webb Simpson for one is gaming an Odyssey with a titleist / Scotty headcover. I'm sure McDowell has always used a White Hot, again, despite having a long term relationship with Cleveland / Srixon. No doubt both are knocking back a few quid from their main sponsor to use off brand putters.

As for the Exo, I'd guess it's just a case of not wanting to dilute their marketing by having too many lines on the go at the one time.
