Wait until you get to the pro level. Should happen fairly quickly for you. The options for clubs are way better-clubs you can't buy until you get to that level. Master level has even more.
In the meantime you can do 2 things to bring yourself up to speed. Read the Putting Tips in the FAQ. Great info complete with pics that will let you nail your putter down. The Chip and Pitch should be the second move. Both of these tutorials were written by players here and are updated. The author of the Putting Chips, WGTNiv (formerly nivlac) also produced a required reading (IMO) comparison of all the clubs in the pro shop. See this thread....

You can find the answer to your increment question by using the search box. I'd tell you but I've never had that putter. LOL-You won't have it for long either given that it's 1/2 as accurate as the 2 top ones. GL
p.s., Posting ranked stroke rounds is what changes your average and nobody is really sure where it changes. Pro to Master is somewhere around 66. You can play these rounds in the weekly tournaments, multiplayer or by yourself (leftmost tab on game window.) They need to be ranked to count.
