Odyssey o-works #1 vs #1w

Hi all,

Given my recent post about putter grips, I’ve actually been offered an o-works #1W at a decent price.

I’d been looking for an excuse to get a new putter so I guess I’ve got one now 😂

My current putter is the same style as the #1 so I was wondering, other than the head size, is there any difference between the #1 and #1W?

Weight, balance, type of shaft or anything?
