TWU Professor: Plans to Coordinate Spin Data?

Hey TW Prof!

I'm a huge fan of your spin research and am curious as to whether or not there are plans to "sync" or coordinate your data across the various spin-related topics?

For example, in your new string-on-ball data you don't include Focus Hex. But when one follows your (excellent) advice to look up rankings using the static friction string tool by hiding hybrids Focus Hex is at the top! It just seems weird that one wouldn't have coordinated the subject strings when researching the different spin-related topics.

So I'm going to be bold here and suggest some strings for study across all of your various experiments. These suggestions are based on my own trial-and-error activities using bits of your previous spin-related research.

I'd also like to suggest that you examine spin-characteristic longevity. Some of the strings with the lowest friction ratings quickly lose their low-friction characteristics with use as they become "dented".

STRINGS/HYBRIDS SUGGESTED FOR COMPREHENSIVE STUDY:

- VS Touch Black / MSV CoFocus 1.23

- VS Touch Black / MSV Focus Hex 1.18 or 1.23

These hybrids exhibit ultra-low friction between mains and crosses. Even at reference tensions in the high 50s+ one can freely slide the mains back and forth across the crosses and can do so even after extended play. Meanwhile the crosses wear grooves in the mains such that if you move a cross out of position it makes a loud "snapping" noise when you slide it back into place. After trying many different poly cross with VS mains none has come close to this level of extended performance (RPM Blast provides great performance at first but then locks up with extended play...Luxilon crosses lock up the gut mains even faster. Hurricane Feel lasts longer than Blast but not as long as the MSV products).

Yes, I plan to coordinate all the data. For the preliminary research, the main goal was just to see what was happening and to analyze it, not to compare all strings --so I used what I had available. The next job is to test more strings.

Also, all the friction data will appear in one database so that you can see static and sliding inter-string friction along side string-to-ball friction.

Testing the change in friction characteristics over time is a good idea. Each test leads to others. You take what you learn from one test and apply it to another. And there are other tests waiting in line too. We are chipping away at it.

But now ... back to testing racquets. I should (?) have all the new Wilson racquets up by Monday.

Thanks, that great news! Really looking forward to it.

The data has been immensely helpful and the "real world" testing very enjoyable. It has been interesting to see how the lab work compares to performance on-court.

Just as innovations in frame technology led to user-friendly racquets I believe your research is leading to string setups that provide "casually accessible spin". Even with my limited tennis experience I can hit some gravity bending shots. Obviously some proper level of technique is required but these setups clearly enhance whatever limited success I have with my "3.0 technique". :)

Thank you for this tremendous effort.

I look forward to the tests of the Wilson PS6.1 90 BLX. (My second one from TW arrived last night.)
