Comfort Challenge: Hammer vs Mfil300 vs Black Ace

After the overhaul of the hammer (link1)(link2) and mfil300 (link1)(link2), I was asked if I could pitch them against a Pro Kennex. 

I thought it made sense. Which is why I got the Black Ace 98 (link) to do this sinister comparion...

The hammer and mfil300 were strung with poly/syn gut and syn gut respectively. Some may argue it's an unfair competition, but I think the results should still hold and will be pretty fast and decisive.

Only my regular partner, M and myself would be doing the tests.

My objectives are to:
1. understand how an arm friendly racket ought to play like,
2. ascertain if a harsh racket can made to play arm friendly,
3. find out if my frequency based mod is repeatable,
4. satisfy our curiousity.
