I have seen many names used for the waterproof line of Titleist stand bags from various retailers on-line, would appreciate any clarity that can be offered differentiating the following: Players 4 StaDry; Limited Players 4 StaDry; Players 4UP StaDry; and Players 4 Plus StaDry. How many different versions (irrespective of color choices) of StaDry stand bags are on the market right now (not just 2019, but 2018 as well since those are still widely available)? what are the differences in terms of weight, # pockets, etc? is there a new version coming out any time soon? Thank you for any light you can shed on these topics.
