Racquet Selection Map now available on-line

The popular and handy Racquet Selection Map is now available in an enhanced on-line version for USRSA members. With a full, sortable table of available racquets, and a larger, zoomable racquet map, the Racquet Selector Map on-line is definitely easier to use. Plus, both the usable tips and FAQ have been expanded, and there are even links to previous years' Racquet Selection Maps.

USRSA members can check it out in the Tools menu, or at:

usrsa.com/members/tools/racquet_map.html

Updated: String Specs tool

USRSA members will be interested to learn that the String Specs tool has been upgraded. It's still sortable, but now the sort is better at handling columns of numbers. Also, the "Company" and "String" columns have been combined into one for display purposes, although you can still search for company and/or string separately.

Nerds will note that while upgrading the String Specs tool, we also upgraded the menu system, tab system, and data table sorting routines site-wide, but with any luck, non-nerds won't notice a thing.

Revamping our on-line calculators

Along with the general move to freshen up the site, we've redone virtually all of our JavaScript calculators to make use of the object literal format, to avoid namespace collisions with other JavaScript elements on our pages.

This in turn has allowed us more easily to combine related tools so they appear on one page, such as the four tension tools (constant-pull to lockout converter, lockout to constant-pull converter, pounds to kilos converter, and the tension estimator) and the two twist weight tools (the calculator and the estimator). The pages for these tools also have a nice tabbed interface for selecting your calculator of interest.

As always, of course, these on-line calculators are available to USRSA members only. If you're not a member, join today!

2008 Masters Cup stringing log now available

Thanks to the PACIFIC stringing team, we have the stringing log for the 2008 Masters Cup in Shanghai. USRSA members can search our Pro Equipment Log database, and sort the results. The 220 records in this stringing log bring our total entries to 6,562 in our pro log database. If you're not a USRSA member, join now to see this great data. Of course, there are many other reasons to join!

Expanded pro log for the 2007 Acura Classic

A new data management tool (Panorama database program, from Provue) has allowed us to make available the full stringing log from the 2007 Acura Classic, which was handled by our own Dave Bone and our trusty Babolat Star 5. Previously, we'd published an overview of the stringing log, but with our new capabilities we've replaced the summary with the full log. For those interested in such things, Panorama also allowed us to make available the full U.S. Open 2008 stringing log, which arrived in "crosstab" format from Wilson. Using Panorama and some devious data manipulations, we were able to "de-crosstabify" the data to fit our report template.

The bottom line is that there are now 160 more data points in the pro stringing log database for USRSA members to search and sort.

Tennis player birthdays

We've augmented our list of tennis player birthdates significantly, adding 11,143 new tennis player birthdates to our searchable listing. This brings the total to 29,383 tennis players for whom we have birthdate information. Check it out.

U.S. Open 2008 pro equipment listing

Thanks to Ron Rocchi and the Wilson Stringing Team, we have added 2,156 new pro equipment listings to our Pro Equipment Log, which is available to USRSA members. This represents an expansion by 53 percent to our previous -- and already extensive --  pro equipment listings.

This gives us a total of 6,158 player equipment listings, most of which show the racquet make and model, string make(s) and model(s), and tension(s) for each player, as well as the name of the event and the year for that equipment combination.

The listing is searchable, and the results are sortable.
